What Is 95kPa Specimen Transport Bag?
A 95kPa specimen Transport bag is an essential tool for the secure and compliant transport of Category B biological substances. Designed to withstand pressure changes that occur during air transport, these bags protect specimens from leaks or contamination, ensuring that they remain safe throughout their journey.

Why Is the 95kPa Rating Important?
The 95kPa rating ensures that the transport bag can handle the pressure fluctuations that occur at high altitudes, especially during air travel. The internal pressure within cargo holds often drops, and the 95kPa specimen transport bag maintains its integrity, preventing any biological substances from leaking and causing potential hazards.
How to Use a 95kPa Specimen Transport Bag Correctly
Using a 95kPa specimen Transport bag correctly is crucial for maintaining compliance with international regulations, such as UN3373. Here’s a step-by-step guide on how to use the bag effectively:
Step 1: Prepare the Primary Container for Transport
Before placing your biological specimen into the 95kPa specimen Transport bag, ensure that your primary container is sealed and ready for transport.
Seal the Primary Container: Ensure that the vial or tube is tightly sealed to prevent leakage.
Label Clearly: Label the primary container with the necessary patient or study identifiers.
Absorbent Material: Place absorbent material around the specimen in case of a container failure, ensuring that any accidental spills are contained.
Step 2: Place the Primary Container Into the Secondary Container
To add an extra layer of protection:
Use a Secondary Container: The secondary container, such as a plastic vial holder, should be sealed securely.
Purpose: The secondary container helps contain any leaks or spills, ensuring the specimen remains safe even if the primary container fails.
Step 3: Insert the Container Into the 95kPa Specimen Transport Bag
Once the specimen is secured in the secondary container, place it inside the 95kPa specimen transport bag.
Place the Container Properly: Insert the sealed secondary container into the bag, ensuring that it fits snugly.
Add Documentation: Place all necessary paperwork, such as test forms and air waybills, in the bag’s external document pocket to keep them dry and separate from the specimen.
Step 4: Seal the 95kPa Bag for Transport
Proper sealing of the 95kPa specimen transport bag is critical:
Seal the Bag Securely: Use the tamper-evident adhesive to ensure a strong, leak-proof seal.
Double-Check: Run your fingers along the entire adhesive seal to make sure it’s properly closed. This step prevents any accidental opening during transport.
Step 5: Label the Bag for Compliance
Ensure that your 95kPa specimen transport bag meets all necessary regulatory requirements:
UN3373 Labeling: Clearly mark the bag with the UN3373 symbol and the wording “BIOLOGICAL SUBSTANCE, CATEGORY B.”
Shipping Information: Include both sender and recipient details on the bag.
Hazard Labeling: For air transport, ensure that you have the necessary hazard labels affixed to the outer box.
Step 6: Use an Outer Rigid Packaging
Place the sealed 95kPa specimen transport bag inside a rigid outer box. This is essential for protecting the specimen from physical damage during shipping.
Outer Packaging Requirements: Use a sturdy box made of cardboard or other suitable materials. Add cushioning, like bubble wrap or packing peanuts, to prevent shifting.
Seal the Outer Box: Secure the box with strong packing tape, ensuring that it is sealed properly before shipment.
Key Considerations for Safe and Compliant Transport of Biological Specimens
Using a 95kPa specimen Transport bag isn’t just about sealing a bag and shipping it off. Proper use ensures compliance with regulations and safety:
Regulatory Compliance: Make sure you’re following IATA and ADR regulations regarding the transport of Category B biological substances.
Safety: Proper packaging prevents contamination or exposure to hazardous materials. By using the 95kPa specimen transport bag correctly, you help safeguard everyone involved in the process.
Common Mistakes to Avoid When Using a 95kPa Specimen Bag
There are several common errors to watch out for when preparing biological specimens for transport:
Incorrect Sealing: Failing to seal the 95kPa specimen bag properly can result in leaks.
Incorrect Documentation Placement: Never place paperwork inside the main specimen compartment. Always use the designated document pocket to keep forms safe and dry.
Overloading the Bag: Avoid placing too many items inside the bag, as this could compromise the integrity of the seal and lead to punctures.
