20 litre liquid nitrogen dewar is a vacuum-insulated storage vessel designed to hold liquid nitrogen at minus 196 degrees Celsius. In IVF and research laboratories, it is used for storing biological samples including embryos, oocytes, sperm and cell lines. The compact size makes it suitable for laboratories with limited bench or floor space that still require reliable cryogenic storage.
