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

Versapak medical carriers are equipped with Thinsulate™, padded protective insulation that maintains the temperature of the contents for up to 12 hours. These robust medical carriers provide laboratories and other medical users with a safe, secure and efficient way to manage any temperature sensitive biological material such as specimens and samples. Not only that, Versapak medical carriers are fitted with internal pockets to hold freezeboards that extend the thermal performance and a pocket for a temperature monitor devices that record the internal temperature, giving you peace-of-mind. Medical carriers with external temperature displays are also available so there is no need to open the carrier to check the internal temperature.

Tested and approved

Versapak’s have been rigorously tested and checked to perform to industry 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 for an average of up to 12 hours. Our largest medical carriers (PYTB3 30 litre internal capacity) performed beyond that maintaining the temperature for over 20 hours. Thanks to the Thinsulate™ insulation of a Versapak Medical Carrier, you can be assured that sensitive specimens or samples needed for examination are received safely and securely.

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 or barcode. This gives the receiver confidence that, as long as the 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.
