The DS-3 Vapour Shipper is designed for the safe transportation of biological samples at cryogenic temperatures. Fabricated from durable, lightweight aluminium, the DS-3 contains a hydro-phobic absorbent which holds the liquid nitrogen. The absorbent also repels moisture and humidity, assuring the maximum holding time. A protective shipping carton is available for all models which protects the container from being placed on its side and helps in withstanding the rigors of transportation. These containers can be used to ship your samples with a "non-hazardous" classification throughout the world.
