Refrigerators, freezers, and cryogenic equipment are designed for the cold storage of samples that are used in industrial, clinical, and research laboratory settings. Cryogenic equipment is used to store samples in liquid nitrogen (-196°C to -210°C). Freezers are available in a variety of formats and sizes, including upright, chest, and countertop. Insulated containers maintain a constant temperature to help protect temperature-sensitive materials during benchtop use, short- or long-term storage, or transport. Refrigerator and freezer accessories include repair components, replacement parts, and support products that are specifically intended for cryopreservation systems.
