Designed for the international transport of specimens, these canisters can be used with primary containers, absorbent materials, and a rigid outer container such as a box to conform to IATA Packing Instruction 650 for Biological Substances.

The 5 tube canister is made of translucent PET material with a screw-cap closure and a special liner to ensure watertight transportation. The 12 tube container features an O-ring gasket that creates a tight seal for watertight transportation.
