Maintaining the integrity of specimens within a cold-chain with Versapak (PYTB) medical carriers

Scientific research institutes around the world use Versapak’s Medical Solutions for transporting specimen samples to and from their laboratories in a protected, secured, tamper evident manner so that they can show a chain-of-custody. Our Medical Carriers are UN3373 certified so that Category B, Biological Substances can be moved safely when following packing instruction P650.

Tested and approved

Versapak’s Medical Solutions are tested and checked to perform to laboratory needs by working with world renowned packaging testing organisation TÜV SÜD Product Service GmbH. They found our insulated carriers can maintain temperatures of 2-8⁰C degrees by an average of up to 12 hours. Thanks to the Thinsulate™ Insulation of a Versapak Medical Carrier, you can be assured that sensitive specimen samples needed for examination are received untouched and unimpeded.

Tamper Evident by Design

For security, Versapak Medical Carriers are fitted with our patented T2 Locking System. This offers users absolute peace-of-mind that the contents have not been tampered with. Using our unique system, a T2 Security Seal is placed in the chamber with a unique identification number. This gives the receiver confidence that, as long as this seal and number is in place as specified by the sender, no-one else has accessed the sensitive items inside.

1. Patented T2 Seal clicks in place with a push
2. Large face plate for unique serial/barcode ensures the ‘chain of custody‘
3. Two legs lock in place of the zip to prevent covert entry
4. Security seal is 100% Recyclable
5. Once secured, the items are impossible to access without evidence of tampering.
