Liquid Nitrogen Dry Shipper
Liquid nitrogen dry shippers are specialized containers designed to transport biological samples at extremely low temperatures without the risk of spills. These devices utilize an absorbent material that soaks up the liquid nitrogen, ensuring there is no free-flowing liquid inside the container. Properly prepared dry shippers are considered non-hazardous and are permitted in both carry-on and checked baggage.
