It greatly increases the success rate of venipuncture and reduces the pain of repeated needling

Pain point: For infants and young children, obese patients, the elderly, those in shock or those who have been receiving intravenous fluids for a long time, their blood vessels are usually thin, deep, brittle or hard to reach. Nurses may need to make multiple attempts to successfully puncture.

Advantages: Venous visualization devices can directly project real-time images of blood vessels onto the skin surface, like a “vascular map”, allowing medical staff to clearly see the location, direction and bifurcations of blood vessels. This achieves “precise puncture”, avoiding the need for multiple needle pricks caused by repeatedly searching for blood vessels, significantly reducing the patient’s pain and fear.



2. Significantly improve the experience of patients, especially those in special groups

Children and infants: Children have thin blood vessels and are very afraid of pain and being touched by strangers. Repeated injections can cause great psychological pressure to both children and parents. The vein finder can quickly locate blood vessels, shorten operation time and soothe the emotions of parents and children.

Elderly patients: The blood vessels of the elderly have poor elasticity and are prone to rolling, and their skin is loose. Visualization technology can help nurses find the most ideal and solid puncture point, avoiding vascular rupture or bruising.

Obese patients: Thick subcutaneous fat completely conceals the visual and tactile cues of blood vessels. The vein finder can “penetrate” the surface fat and reveal the deep blood vessels, solving the biggest problem.

Patients with cancer or chronic diseases: Long-term chemotherapy or intravenous infusion can damage blood vessels, leading to their hardening and fragility. Using a vein finder can select relatively healthy vascular segments for puncture, protecting the patient’s precious vascular resources.



3. Enhance safety and reduce the risk of complications

Reduce vascular damage: Precise puncture reduces accidental injury to the vascular wall, thereby lowering the probability of post-puncture bruising, hematoma, and phlebitis.

Avoid accidental arterial puncture: In some cases, arteries and veins are very close to each other. Clear vascular images can help medical staff distinguish between arteries and veins and prevent accidental puncture of arteries. It is especially an important safety aid for inexperienced operators.

Protecting blood vessels: For patients who need long-term intravenous infusion, the puncture sites can be rotated in a planned manner to avoid excessive damage to the same blood vessel.



4. Shorten the preparation time and improve the efficiency of medical treatment

In busy emergency rooms, outpatient clinics or physical examination centers, it is crucial to quickly establish intravenous access. The use of a vein finder can quickly locate blood vessels, significantly reducing the preparation and search time before puncture, accelerating the overall diagnosis and treatment process, and reducing the time patients spend waiting and being exposed to a tense environment.



5. Alleviate psychological anxiety and fear

For many people, "getting an injection" itself is a source of fear. When patients see medical staff looking troubled because they can't find the blood vessels, it intensifies their sense of tension. When the device clearly displays the blood vessels and the medical staff confidently succeed in one attempt, this "visualization" technology will bring great psychological comfort and trust to the patients, thus increasing their cooperation.

Key Point One: Imaging technology and clarity

This is the core indicator, which directly determines the practical effect of the equipment.

Core technologies: Currently, there are mainly two mainstream technologies, namely infrared imaging and ultrasonic imaging. Infrared light equipment is non-contact and forms images based on the differences in the absorption of near-infrared light by hemoglobin in blood vessels. Ultrasound, on the other hand, directly observes the structure of blood vessels and blood flow through sound waves.

Image quality: Focus on the resolution, contrast and depth of the imaging. High-quality imaging devices can present clear vascular images that contrast sharply with the surrounding tissues on patients of different skin colors and body weights. Especially for deep and tiny blood vessels, whether they can be clearly displayed is the key.

Real-time performance: The image should have no delay and be able to follow the movement of the probe in real time, which is crucial for the dynamic puncture process.



Key Point Two: Patient adaptability and safety

The equipment must be capable of serving a wide range of patient groups and be absolutely safe.

Skin color adaptability: Excellent equipment should have the ability to overcome “skin color bias”, effectively imaging both fair and dark skin. Find out if the device has special calibrations or modes for different skin tones.

Body type adaptability: For patients with obesity, edema or emaciation, whether the penetration ability and imaging effect of the equipment are stable.

Safety level: Confirm that the light source energy of the equipment is within the absolutely safe range of non-ionizing radiation and has obtained the relevant medical device registration certification.



Point Three: Ease of use and workflow integration

The equipment needs to be integrated into the existing clinical process rather than adding to the burden.

Ease of operation: Can the device be used immediately upon startup? Is the calibration process complicated? Is the interface intuitive? Ideally, nurses or doctors should be able to get started after a brief training.

Portability and Design: Is the device Handheld Vein Finder or desktop Vein Finder ? How is the battery life? Whether it is lightweight and ergonomically designed, making it convenient to move and use between wards, emergency rooms and operating rooms.

Sterility and disinfection: Are the parts that come into contact with patients easy to clean and disinfect? Are disposable sterile protective covers provided? This is directly related to infection control.



Key Point Four: Functionality and Augmented Reality Experience

Advanced functions can significantly enhance clinical value.

AR augmented reality projection: Many modern venous imaging devices can directly project vascular images onto the patient’s skin, achieving “what you see is what you get”, allowing the operator not to switch their line of sight back and forth between the screen and the skin, greatly improving the success rate of puncture and the user experience.

Vascular recognition mode: Is there a special mode, such as only showing arteries or veins (by identifying the direction of blood flow), which is very important for certain special treatments?

Image and data Management: Does the device support image taking, archiving, or connection to the hospital information system? This is of certain value for case recording, teaching and remote consultation.

At dawn in the Amazon rainforest, biologist Elena meticulously secures a rare microbial sample—a potential key to combating antimicrobial resistance or unlocking breakthroughs in carbon sequestration. Its scientific value is immeasurable, but its efficacy hinges on a successful 8,000-kilometer transit to a state-of-the-art laboratory at ETH Zurich. 

 

For this critical mission, Elena relies on a paramount protector: Advance International Corp’s 95kPa specimen transport bag, engineered to safeguard biological materials against the most formidable transit challenges.

 

The Gauntlet of Transit

 

The 48-hour journey is a rigorous test of the sample's viability and the bag’s structural integrity. Its performance is decisive:

 

• 6-Hour Overland Transit: The bag’s shock-absorbing liner effectively isolates the primary receptacle from external forces, ensuring sample stability during jarring off-road travel. Its 95kPa pressure resistance provides an essential buffer against impact damage, a critical feature when navigating rough terrains at vehicle tilts exceeding 30°.

 

• 12-Hour Transatlantic Flight: Utilizing a multi-layered EVOH barrier film, the bag maintains a stable microenvironment with a relative humidity of 45%±5%. This thermal insulation prevents the sample from succumbing to extreme temperature fluctuations (32°C to -5°C) encountered within pressurized aircraft cargo holds.

 

• 2-Hour Sun Exposure Delay: A specialized UV-resistant coating on the outer layer provides superior photoprotection, blocking over 90% of harmful UV radiation at Amsterdam Airport. This prevents photo-degradation and a loss of microbial viability often caused by heat stress.

 

“Previous sample losses due to subpar packaging cost us six months of research,” Elena notes. “The structural durability of this bag kept our sample perfectly intact—no spillage, no contamination.”

 

Safe Handover and Scientific Validation

 

On Monday morning, Zurich-based researcher Lukas receives the consignment. The bag's clear UN3373 compliance mark and “95kPa Pressure Tested” seal serve as visual confirmation of its integrity. Under the microscope, the microbes are confirmed to be fully viable. Within 72 hours, gene sequencing reveals a peptide that exhibits potent MRSA inhibition—a monumental breakthrough in antibiotic development.

 

“Scientific breakthroughs often hinge on unseen details,” Lukas states. “Advance’s 95kPa bag is more than just packaging; it is a critical enabler that bridges a remote rainforest discovery with tangible medical progress.”

 

Safeguarding the Global Path to Innovation

 

Today, that rainforest sample is the foundation of a landmark, peer-reviewed study. Concurrently, Advance International Corp’s specimen transport bags continue to safeguard an array of critical cargo: ancient bacteria from the Antarctic, epidemic blood samples from Africa, and extremophile organisms from deep-sea vents. Each bag carries more than a sample—it transports humanity’s relentless drive to explore, heal, and innovate.

 

Behind every game-changing scientific discovery lies a quiet hero: the robust integrity that links the wilderness to the lab. For Advance International Corp, that integrity is meticulously engineered into every 95kPa specimen transport bag.

Last Wednesday, I panicked mid-shipping prep: I needed to send inactivated COVID-19 specimens to a lab 20km away, but I’d only grabbed a random zip-top bag—no proper specimen transportation bag in sight. My advisor’s warning hit fast: “A leak without a certified biohazard bag means wasted work, violations, and risk to couriers.” I rushed back to the lab, scrambling to sort through supplies, only to get stuck on basics: What’s the difference between a UN2814 biohazard bag and a UN3373 specimen bag? How do I pick a bag that keeps specimens safe, even with gel packs?

 

After an hour of stress (and a lifeline from our senior tech Maria), I finally repacked with the right gear. Later, I dug through lab logs and realized 80% of shipping disasters happen not because of specimens, but because of wrong specimen transportation bags or bad packing. Here’s what I learned—with the key terms you need to shop for and use these bags right.

 

Pick Your Specimen Transportation Bag by Risk: UN2814 (95kPa Bag) vs. UN3373

 

My first big mistake: Grabbing a blue UN3373 specimen bag for viral specimens. Maria stopped me cold: “That UN3373 bag is only for low-risk loads—like routine patient blood or fixed tissue. Viral specimens need a UN2814 biohazard bag.”

 

Why the difference? It all comes down to safety features:

 

• UN3373 specimen bag: A basic leak-proof bag that passes 1.2m drop tests. Great for local trips with non-pathogenic specimens (e.g., non-infectious cell cultures). It’s not built for high pressure or dangerous materials.

 

• UN2814 biohazard bag: This is a 95kPa pressure-resistant bag—critical for air shipping or high-risk specimens (viruses, live bacteria). The 95kPa rating means it can handle the pressure changes of flights without leaking, and it usually has a secondary inner liner to catch spills.

 

• Pro tip: When shopping for a specimen transportation bag, check the label first. A UN2814 biohazard bag will clearly mark “95kPa pressure-resistant” and have a bright red biohazard symbol. A UN3373 specimen bag is often blue or clear—don’t mix them up!

 

3-Step Packing for Your Specimen Transportation Bag (No Shortcuts)

 

Even the best specimen transportation bag fails if you pack it wrong. Maria walked me through a routine that protects specimens (and avoids leaks):

 

• Seal specimens first, then bag: Wrap centrifuge tube caps in parafilm to stop loosening; slide cryovials into foam sleeves (skip this, and you’ll crack vials—trust me). Only then place them into the specimen transportation bag’s main compartment.

 

• Use the bag’s two chambers (if it has them): Most quality specimen transportation bags have separate pockets—one for specimens, one for paperwork + temperature strips. Never mix! A leaky specimen ruins docs, and the receiving lab can’t verify your load.

 

• Match cooling to your bag (for temperature-controlled shipping): For 2–8°C specimens, use 2–3 pre-frozen gel packs inside the specimen transportation bag (not loose!). For -80°C ultra-low temp needs, add dry ice—but wrap it in paper towels first! Direct dry ice contact can crack vials, even in a tough UN2814 biohazard bag.

 

Label Your Specimen Transportation Bag Like It Matters (Key Tags Included)

 

I almost had the courier refuse my UN2814 biohazard bag—I forgot to add proper labels. Here’s what must go on any specimen transportation bag:

 

• Orange/black biohazard symbol (required for all UN2814/UN3373 bags, per IATA rules).
• UN number: Clearly mark “UN2814” or “UN3373” on the bag—couriers use this to handle your specimen transportation bag safely.
• Contact info: Your number + the receiving lab’s—critical if the specimen transportation bag gets delayed or damaged.
• Optional (but smart): Humidity strip (turns blue if wet) and temperature strip (for temperature-controlled specimen shipping)—saved me last week when condensation looked like a leak!

 

Wrap-Up

 

The right specimen transportation bag isn’t just a “bag”—it’s your specimen’s first line of defense. For high-risk loads, grab a UN2814 biohazard bag (that’s the 95kPa pressure-resistant one!). For routine samples, a UN3373 specimen bag works. Pack carefully, label clearly, and you’ll skip the panic I felt.

When the U.S. FDA announced its June 2025 ban on shipping U.S. clinical trial samples to “adversary nations” like China and Russia, the global biotech industry felt an immediate jolt. For U.S. biotechs, the loss of access to China’s high-throughput sequencing services—relied on by ~30% of U.S. clinical trials—threatened supply chain disruptions. For labs and manufacturers worldwide, it also raised the stakes: any clinical sample transport now demands stricter compliance, leak-proof safety, and global logistics resilience to avoid costly delays or regulatory penalties.

At AIC Biological Bag, we’ve built our solutions to address exactly these challenges. As a leading supplier of UN3373-compliant specimen transport bags and kits, we help biotech firms, clinical labs, and CROs (like your partners IQVIA and Labcorp) stay agile—even when policies shift. Below’s how the FDA ban is reshaping sample transport, and how AIC’s products keep your operations on track.

 

The FDA Ban’s Ripple Effect: What It Means for Global Sample Transport

 

The FDA’s policy reversal isn’t just a U.S.-China issue—it’s a wake-up call for the entire industry to prioritize two non-negotiables: regulatory compliance and supply chain reliability.

 

• Compliance Scrutiny Is Tighter Than Ever

With the FDA framing sample transport as a “national security” issue, customs and health authorities worldwide are stepping up inspections of cross-border shipments. Any sample bag that fails to meet international standards (like UN Regulation PI650 or UN3373 for biohazard materials) risks being held or rejected—delaying trials and wasting valuable specimens. 

 

For example, a U.S. biotech recently saw a batch of blood samples detained at a European port because their transport bags lacked 95kPa pressure certification, a key benchmark for leak resistance.

 

• Supply Chain Diversification Becomes Critical

The 30% reliance on China’s sequencing services has forced U.S. firms to seek alternative partners in regions like Southeast Asia or Europe. This shift means longer transport routes—and a greater need for durable, temperature-stable packaging that protects samples from turbulence, temperature fluctuations, or accidental drops. 

 

AIC’s clients in Singapore and Germany, for instance, now use our ai650 series for 72-hour transcontinental shipments, with zero leakage incidents.

 

• Risk Mitigation Is Non-Negotiable

The FDA’s lack of specific “violation examples” has left companies guessing about what qualifies as “high-risk” transport. To avoid gaps, labs and CROs are doubling down on safety features: absorbent pouches to contain spills, tamper-proof seals to prevent contamination, and independent document pockets to keep customs forms separate from samples. These aren’t just “nice-to-haves”—they’re essential for passing audits and maintaining trust with partners.

 

How AIC’s Solutions Address the FDA Ban’s Challenges

 

AIC’s product line—built around the 95kPa-certified ai650 series and UN3373-compliant accessories—directly solves the pain points of post-FDA-ban transport. Here’s how we support your operations:

 

1. UN-Certified Compliance: Pass Inspections Every Time

 

All AIC specimen transport bags (including the best-selling ai650 model L300420) are factory-tested to meet UN Regulation PI650 and UN3373 standards—the global gold standard for biohazard sample transport. Our 95kPa pressure certification ensures bags resist the physical stress of air cargo (turbulence, pressure changes) and accidental handling, eliminating the risk of leaks that could get shipments detained.

 

For U.S. firms shipping to alternative partners in Europe: Our bags align with EU 《Animal By-Product Regulation》 (EC 1069/2009), a common requirement for clinical sample imports.

 

For Chinese labs working with non-U.S. clients: Our compliance with IATA’s Dangerous Goods Regulations (DGR) ensures smooth clearance in 180+ countries.

 

2. Customized Kits for Diversified Supply Chains

 

The FDA ban has pushed companies to rethink their transport routes—and one-size-fits-all packaging no longer works. AIC’s customized kit assembly service lets you tailor solutions to your specific needs:

Small-batch shipments (e.g., 6*9inch blood sample bags for regional labs in Southeast Asia).

 

Large-volume trials (e.g., 7-slotted absorbent pouches (APS4X320) for UN 2814/2900 substances, used by our client Fortrea for cell therapy samples).

 

End-to-end logistics support: We leverage our Shanghai port proximity (3 hours by train from our Yangtze River Delta factory) to cut delivery times for global shipments—critical for time-sensitive clinical samples.

 

3. Trusted by Industry Leaders (Even Amid Uncertainty)

 

In times of policy chaos, partnering with a reliable supplier matters. AIC’s long-standing relationships with top CROs and biotechs—including Parexel, Labcorp, and ERGOMED—speak to our consistency. For example:

A U.S.-based biotech recently switched to AIC’s ai650 bags to ship samples to a new partner in South Korea. Their first 10 batches cleared customs in 48 hours, with no compliance issues.

 

A Chinese diagnostic lab used our absorbent pouches to safely transport COVID-19 test samples to Australia—meeting both WHO’s biohazard guidelines and local customs requirements.

 

Beyond the Ban: Building Long-Term Transport Resilience

 

The FDA’s 2025 policy isn’t just a temporary disruption—it’s a signal that global sample transport will only grow more complex. To stay ahead, biotech firms need partners who don’t just sell packaging, but offer end-to-end peace of mind:

AIC’s R&D team updates products quarterly to reflect new regulations (e.g., recent tweaks to our ai650 seal design to meet FDA’s latest “tamper-evident” guidelines).

Our after-sales team provides 24/7 support for customs questions—critical when shipping to new regions.

We offer OEM/ODM services to help you build branded, compliant kits that align with your global branding (e.g., custom document pockets with your lab’s logo).

Whether you’re a U.S. biotech diversifying your sequencing partners, a Chinese lab expanding to non-U.S. markets, or a CRO managing cross-border trials, AIC’s 95kPa-certified solutions keep your samples safe, compliant, and on time—no matter what policies come next.

In the critical field of biological specimen transportation, "selecting the correct packaging" serves as the primary line of defense to ensure sample integrity and regulatory compliance. Different scenarios present unique challenges: hospitals fear "wasting space with large bags, or insufficient space with small ones" for blood samples; clinical research demands stringent separation to prevent "cross-contamination" among multiple specimens; and international shipping risks "non-compliance detentions by customs."

 

To address the core needs of these diverse applications, AIC's specialized transport bag series, including the ai650, L300420, and APS4X320, are each strategically designed. This article will provide a precise needs-matching solution through a "Scenario-Based Selection Guide + Parameter Comparison + Customization Options," helping you accurately select models and avoid common pitfalls.

 

Scenario-Based Selection: Prioritize Transport Needs,Then Match the Model

 

1. Hospitals / Health Check Centers: Short-Haul Blood/Urine Specimen Transport — Prioritize "Small Size + High Transparency"

Core Needs: Small sample volume per trip (typically 1-2 test tubes), short transport distance (inter-departmental or intra-city), and the need for rapid specimen information verification (to avoid repeated opening of the package).

 

Recommended Model: 6x9 inch 95kPa Blood Specimen Transport Bag (A standard variant of the ai650 Series)

 

Why Choose This?

 

Optimal Size: The 6x9 inch (approx. 15 cm×23 cm) size perfectly accommodates 1-2 standard 5−10 ml blood collection tubes. The compact bag is lightweight, easily carried by medical staff, or fits into a care kit, preventing "oversized packaging" which can lead to sample agitation.

 

Material Advantage: Made from high-clarity Polyethylene (PE) material, it allows for visual verification of patient information and specimen ID on the tube label without opening the package, reducing the frequency of openings and minimizing contamination risks.

 

Basic Protection: Compliant with UN3373 and PI650 standards, its 95kPa pressure resistance handles common intra-city transit jolts (e.g., ambulance braking, elevator movement). Paired with a thin integrated absorbent layer, it can contain small amounts of condensation or minor accidental fluid leaks.

 

2.Clinical Research Institutions: Multi-Specimen / Multi-Site Transfer — Essential: "Compartmentalized Absorbent Bags"

Core Needs: Transportation of multiple specimens in a single shipment (e.g., 4-7 blood/CSF samples from different subjects), the requirement for strict segregation to prevent cross-contamination, and a robust defense against "leakage in the event of sample damage."

 

Recommended Model: APS4X320 4/7 Compartment Absorbent Bag (Used in conjunction with the ai650 Outer Packaging Bag)

 

 

Why Choose This?

 

Physical Segregation: The bag features 4 or 7 independent retention slots (card slots), each securing 1 test tube or small vial. This complete separation prevents tube collision during transport, thus avoiding label abrasion and specimen mixing.

 

Superior Absorption: The absorbent layer within the slots utilizes Superabsorbent Polymer (SAP), capable of absorbing up to 50 ml of liquid per slot (equivalent to the full volume of a standard test tube). Should a primary receptacle break due to impact, the leaked fluid is instantly immobilized, preventing wicking to other slots or the outer bag.

 

Broad Compatibility: It accommodates not only standard blood collection tubes but also 15 ml centrifuge tubes and 20 ml reagent vials, making it ideal for clinical studies requiring the "transfer of multiple specimen types in one batch."

 

3. International Biopharma / Cross-Border Labs: Long-Haul Air / Sea Freight — Essential: "Fully Compliant ai650 Series"

 

Core Needs: Passing UN3373 compliance checks by customs in regions like Europe, the Americas, and Southeast Asia; withstanding pressure changes during long-haul transport (e.g., high-altitude low-pressure environments in air freight); and ensuring long-term preservation of specimen labels and documentation.

 

Recommended Model: ai650 95kPa Certified Model (Can be paired with a separate Document Pouch)

 

 

Why Choose This?

 

Full Compliance: The bag is pre-printed with the UN3373 Biohazard Mark and the 95kPa Pressure Certification Seal. It comes with a manufacturer's Certificate of Compliance (ready for submission to customs). This simplifies adherence to international regulations such as the IATA DGR (Dangerous Goods Regulations) and US DOT rules, preventing delays or detentions due to "incomplete labeling."

 

Pressure and Stress Resistance: Subjected to simulated air transport pressure tests (repeated pressurization from −50 kPa to 95 kPa), the bag demonstrated no rupture or leakage. It is built to withstand the rigorous conditions of long-haul transportation, from China to Europe (approx. 12 hours air freight) or China to Southeast Asia (approx. 3 days sea freight).

 

Document Protection: Features a separate external document pouch for insertion of the specimen manifest, customs declaration forms, and test reports. This ensures the documentation is completely isolated from the specimens (preventing liquid contamination of documents) and the pouch uses waterproof material, protecting the paperwork even if the outer package encounters rain.

 

3 Steps to Quickly Identify the "Optimal Solution

 

Define the Scenario: First, clarify the nature of the transport: "Short-haul / Long-haul," "Single Specimen / Multiple Specimens," and "Standard / Special Environment" (e.g., cryogenic, radiation).

 

Match Parameters: Compare the scenario against the "Parameter Comparison Table," prioritizing "Regulatory Certification" and "Size" (e.g., international transport must check UN3373, multi-specimen transport must check the compartmentalized design).

 

Inquire About Customization: If standard models are insufficient (e.g., for extra-low temperature or large volume), directly contact the customization service to avoid using standard bags that introduce risk.

 

If you are still uncertain about the selection process, please contact the AIC Technical Team at www.aicbiologicalbag.com. Provide your specimen type and transportation details, and we will offer a complimentary "Selection Recommendation Report." You may also request free samples for testing, ensuring an accurate and risk-free choice.

From -80℃ Freezing to 60℃ Heat: Which Transport Bag to Choose for Different Biological Samples? (With Advance Selection Guide)​

 

Last week, we received an urgent inquiry from a research institute client: "Nearly a third of our transported blood samples suffered from hemolysis when they reached the lab, costing us half a month of experimental data!" Upon investigation, the issue traced back to the choice of transport bag—they had used ordinary PE bags, which could neither resist temperature fluctuations during transit nor provide anti-hemolysis protection.​

 

In biological sample transportation, "choosing the right bag" matters more than "choosing an expensive one." Different samples (blood, tissues, viral reagents) have entirely different temperature tolerances and biological characteristics, meaning their corresponding transport bags also vary significantly in material, layer count, and protective design. Today, we’ll share a practical selection guide using Advance’s core products (AI650 Bag, Lab Absorbent Pouches) to help you avoid sample loss.

 

I. Blood Samples: Anti-Hemolysis Is Critical—Ordinary PE Bags Are a No-Go!​

 

1. The "Temperature Dead Zone" for Blood Samples​

 

Blood samples (whole blood, serum, plasma) are extremely sensitive to temperature fluctuations:​

 

• During refrigerated storage (2-8℃), temperatures exceeding 10℃ accelerate red blood cell rupture; temperatures below 0℃ cause freezing, and ice crystals pierce cell membranes, directly leading to hemolysis.​

 

• Even for short-distance transport (4-6 hours), the temperature fluctuation range must not exceed ±2℃—otherwise, it will affect subsequent blood routine and biochemical test results.​

A previous client used ordinary PE bags to transport whole blood; a brief cold chain failure in the truck (temperature rose to 12℃) resulted in hemolysis of all 20 samples, causing tens of thousands of yuan in experimental losses.

2. Mandatory Material and Packaging Requirements​

 

• Preferred Material: Five-Layer Co-Extruded Film (Core Material of AI650 Bag)​

 

Ordinary PE bags have flaws: thin thickness (only 0.08mm), poor airtightness, easy oxygen permeation during temperature fluctuations, and potential leaching of trace additives that contaminate samples.​

In contrast, Advance’s AI650 Bag uses a five-layer co-extruded film (LDPE/Tie/EVOH/Tie/ULDPE). The inner layer is medical-grade ULDPE with a leaching rate of less than 0.01%, avoiding reactions with proteins in blood. The middle EVOH layer has an oxygen transmission rate of only 0.3cc/(m²·24h)—90% lower than ordinary PE bags—locking in a stable internal environment and fundamentally reducing hemolysis risks.​

 

For even better results, pair it with Advance’s Lab Absorbent Pouches. This absorbent bag quickly soaks up blood that may accidentally leak due to seal issues (water absorption capacity up to 15x its own weight), preventing cross-contamination of samples while keeping the bag interior dry to further minimize temperature-induced impacts on blood.​

 

• Packaging Layers: At Least Double Layers; "AI650 Bag + Outer Cushion Bag" 

 

Single-layer transport bags cannot withstand extrusion or vibration during transit. We recommend a double-layer structure: "inner AI650 Bag (for samples) + outer cushion bag (filled with bubble wrap)." In our tests, when whole blood-filled AI650 Bags were placed in cushion bags, the sample hemolysis rate was only 0.5% after a 1.2-meter drop test—far below the industry average of 3%.

 

3. Advance’s Test Data for Assurance​

 

• 72-hour refrigerated transport at 2-8℃: Temperature fluctuation inside the AI650 Bag ≤ ±1℃, sample hemolysis rate < 1%.​
• Accidental temperature rise to 30℃ (sustained for 2 hours): Thanks to the EVOH layer’s barrier, the internal temperature only rose to 12℃, not triggering the hemolysis threshold.

 

II. Tissue Samples: Low-Temperature Resistance + Puncture Protection—Even for -80℃ Freezing!​

 

1. The "Preservation Challenge" for Tissue Samples​

 

Tissue samples (e.g., tumor tissues, animal organs) typically require -80℃ freezing for preservation. During transport, it is necessary to maintain low temperatures and prevent sharp tissue edges from puncturing the bag. A client once used ordinary freezer bags to transport tumor tissues; the bag was pierced by tissue edges, and the sample deteriorated rapidly after exposure to air, forcing the experiment to be redone.​

 

2. "Dual Protection" for Materials and Packaging​

 

• Low-Temperature Resistant Material: AI650 Bag’s -196℃ Ultra-Low Temperature Tolerance​

 

Ordinary freezer bags become brittle at -80℃ and crack easily when folded. However, the five-layer co-extruded film of Advance’s AI650 Bag undergoes low-temperature toughness treatment, remaining flexible even at -196℃ (liquid nitrogen temperature) with unchanged sealing performance after repeated folding.​

 

For tissue samples that may leak bodily fluids, pairing with Lab Absorbent Pouches creates "dual protection": the absorbent bag soaks up leaked fluids, preventing them from freezing and puncturing the transport bag. Our clients report that this combination reduces tissue sample transport loss rates from 8% to below 1%.​

 

• Packaging Layers: Three-Layer Protection for Extreme Transport Conditions​

 

A three-layer structure is recommended: "inner AI650 Bag (for tissue samples) + middle Lab Absorbent Pouches (absorbent protection) + outer rigid carton (anti-extrusion)." Especially for frozen tissue transport, dry ice can be placed inside the carton. The AI650 Bag’s low-temperature resistance ensures samples are not damaged by freezing, while the outer carton prevents deformation caused by dry ice sublimation.​

 

3. Advance’s Test Data for Assurance​

 

After 72 hours of freezing at -80℃: The AI650 Bag maintains a 99.8% sealing rate. When the bag is opened, the tissue sample remains intact in shape with no freezing damage or deterioration.​

Puncture resistance test: Pressing a sharp tissue edge (5mm diameter) against the AI650 Bag (50N pressure) for 10 minutes resulted in no damage or leakage.

 

III. Viral Reagents: Biosafety First, with Temperature Stability as a Priority​

 

1. "Dual Risks" of Viral Reagents​

 

Viral reagents (e.g., COVID-19, influenza virus samples) are not only temperature-sensitive (most require -20℃ freezing or 2-8℃ refrigeration) but also pose biosafety risks. If the transport bag is damaged, viral leakage could trigger public safety issues. Thus, compliance with UN Class 6.2 Dangerous Goods Transport Standards is mandatory.​

 

2. "Compliant Design" for Materials and Packaging​

 

• Compliant Material: AI650 Bag Certified by IATA DGR​

 

Ordinary transport bags cannot meet the sealing requirements for dangerous goods transport. However, Advance’s AI650 Bag has passed the International Air Transport Association (IATA) Dangerous Goods Regulations (DGR) Edition 63 certification. Its double-seal design achieves 0 leakage, fully complying with biosafety transport standards for viral reagents.​

 

Meanwhile, the absorbent layer of Lab Absorbent Pouches undergoes antibacterial treatment. Even if viral reagents accidentally leak, the antibacterial components in the absorbent bag inhibit viral activity and reduce spread risks—critical for cross-border transport (e.g., meeting EU IVDR regulatory biosafety requirements for exports).​

 

• Packaging Layers: Designed by Hazard Level, At Least Three Layers​

 

Packaging layers should be adjusted based on the risk level of viral reagents:​

Low-risk viruses (e.g., ordinary influenza viruses): "AI650 Bag + Lab Absorbent Pouches + outer waterproof bag."​

High-risk viruses (e.g., COVID-19): Add an outer rigid carton with biohazard labels to the above structure. The carton must pass a 1.2-meter multi-directional drop test (Advance’s custom cartons meet this requirement).​

 

3. Advance’s Test Data for Assurance​

 

96-hour refrigerated transport at 2-8℃: The activity retention rate of viral reagents inside the AI650 Bag reaches 95%—far higher than the industry average of 85%.​

 

Biosafety test: Simulating a transport bag damage scenario, Lab Absorbent Pouches absorb all leaked reagents within 30 seconds, with an antibacterial rate of 99% and no viral spread risks.
