Refurbished 40 L dewar for cryogenic sample storage with hanging baskets and straws.
The Air Liquide BT 40 is a refurbished liquid nitrogen dewar, perfect for the storage of cryogenic samples using hanging baskets and straws. Featuring a substantial 40-liter capacity, this model provides storage for up to 10 canisters, of which 9 are currently available for use. It features a neck diameter of 80mm and an evaporation rate of 0.5 L/day, with a static holding time of up to 120 days. For added convenience, the unit includes a platform with wheels for ease of mobility.
Liquid nitrogen, with its boiling point at -196 °C, is utilized in both its liquid and gas phases for the long-term preservation of samples. When storing, transporting, or handling liquid nitrogen, it is crucial to use specialized containers, tailored to the volume intended for storage. Samples preserved within liquid nitrogen are typically organized in rack systems, which may be implemented with or without a cryobox, or arranged using straws or rods for optimal sample management.
