Shock-absorbing Foam Inserts Biohazard Shipping Box

The biosafety transport sponge liner is a core cushioning component for the compliant transport of infectious materials and biological specimens. Combined with the UN-certified biosafety transport box, it forms a multi-layered safety system combining "hard shell protection + soft sponge cushioning + sealed container." This system provides critical shock and damage protection for clinical specimens, scientific research samples, biological reagents, and more, meeting the stringent international transport standards for leak and physical damage prevention.

Core Advantages

High-density sponge for ultimate shock and damage resistance

Utilizing high-density polyurethane soft sponge (density ≥ 35 kg/m³), it offers exceptional shock absorption and impact resistance. During transport, it effectively absorbs energy from bumps and collisions, preventing vibration and crushing damage to internal containers such as centrifuge tubes, cryotubes, and specimen bags, thereby reducing the risk of sample leakage or failure.

Precisely pre-cut to securely secure specimens

The sponge liner features a custom groove design to precisely fit common sample container sizes (such as 1.5ml centrifuge tubes, 5ml cryotubes, and specimen transport bags). Once inserted, the container fits snugly and seamlessly, ensuring a rock-solid stability for samples even over long distances or in complex road conditions.

Enabling compliant transportation and meeting international standards

Working in conjunction with UN-certified biosafety transport containers, it meets three core international standards:

• UN 2814 (Category A infectious substances, such as highly pathogenic pathogens);
• UN 3373 (Category B infectious substances, such as routine clinical specimens);
• IATA DGR (International Air Transport Association Dangerous Goods Regulations).

Ensuring worry-free compliance throughout the entire biological sample transportation process.

High-quality materials make cleaning and reuse more economical

The sponge material is lightweight, durable, and contains no corrosive ingredients, preventing contamination of samples or containers. Its smooth, easy-to-clean surface can be quickly disinfected with alcohol wipes or UV disinfection, ensuring a high reusability rate and balancing safety and cost control.

Technical Specifications

Application Scenarios

Medical: Transporting blood, body fluids, and pathogenic microorganism specimens in hospital laboratories and third-party medical laboratories;

Biomedical: Transporting cell lines, viral samples, and diagnostic reagents in biopharmaceutical companies and vaccine development institutions;

Research and Education: Transporting experimental samples, bacterial strains, and gene editing materials in university laboratories and research institutes;

Emergency: Rapidly transporting high-risk biological materials during epidemics and public health events.

Instructions

• Preparation: Place the sample container (centrifuge tube, specimen bag, etc.) to be transported into the pre-cut grooves of the sponge liner, ensuring a tight fit between the container and the sponge.

• Assembly: Place the sample-filled sponge liner into the supplied biosafety transport box. Once the outer box is sealed, it is ready for legal transport.

Frequently Asked Questions (Q&A)

Q1: Can the sponge liner be customized to different sizes?

A: Yes! We support custom pre-cut grooves based on the dimensions of your sample container (such as special centrifuge tubes and reagent bottles) to meet your individual transportation needs.

Q2: Will cleaning and disinfecting the sponge affect its performance?

A: No. High-quality polyurethane sponge has excellent chemical resistance. Conventional methods such as alcohol wiping and UV disinfection will not damage the sponge structure or affect its cushioning performance.

Q3: How do I determine if your sample meets our transportation requirements?

A: Please provide us with information such as sample type (Category A/Category B infectious substances), container specifications, and transportation method (air/land). We will match you with the most compliant transport cushioning solution.
