Ultra-low temperature freezers Also known as minus eighty freezers, a specialized category of laboratory freezers for maintaining temperatures from –20°C to –80°C.
How are ultra-low temperature freezers used? Ultra-low temperature (ULT) conditions can be critical to the safe storage of samples and reagents. ULT freezers typically cool to temperatures between -50°C and -80°C, which is significantly lower than standard freezer temperatures. Ultra freezers are essential equipment in many laboratories, particularly those that require safe short- or long-term storage of materials such as vaccines or temperature-sensitive biological samples, including DNA, RNA, viruses, sera and proteins.
Most ULT freezers are made of sturdy, durable materials, such as stainless steel, aluminum, or powder-coated sheet steel. Customizable internal layouts or compartments are also available. For example, they can have combinations of adjustable and interchangeable doors, shelves, baskets and trays. As accessories you can also purchase special shelving systems, designed to store cryogenic boxes, vial storage systems or cryotubes.
