What is a Liquid Nitrogen Dry Shipper?

Liquid nitrogen "dry shippers" are designed to safely transport biological samples at cryogenic temperatures. These insulated containers are lined with a unique material that absorbs the liquid nitrogen thereby preventing a spill if the unit is tipped over. There is no free liquid in a fully charged dry shipper. Liquid Nitrogen Dry ShipperStorage temperature inside the shipping cavity remains at approximately -150°C for several days until the liquid nitrogen evaporates from the absorbent material.

The NCI Mouse Repository dry shippers are property of the National Cancer Institute and must be returned promptly.
