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). Internal temperatures will remain at or below -196°C when the supply of liquid nitrogen is consistently replenished.

Refrigerators maintain temperatures somewhere between 1° and 12°C. Choose refrigerators with capacities from 1 to 80 cubic feet in under-the-counter, benchtop, or upright configurations. Refrigerators may have single or multiple compartments, internal shelving or drawer formats, and solid or glass hinged or sliding door options.

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. Standard freezer temperatures range from -10° to -30°C. Ultra-low-temperature freezers may have more than one internal doors to help with temperature maintenance and sometimes have keyed locks. Ultra-low-temperature freezers maintain between -50° and -90°C.

Freezers designed for enzyme or plasma storage or for blood banks and pharmacies often have integral temperature recording capabilities and alarm systems to help with regulatory requirements. They can also have flexible internal shelving, sliding drawers, or bins to accommodate specific products or materials. Refrigerators and freezers may also be designed to store flammable or potentially explosive products.

Refrigerator and freezer accessories include repair components, replacement parts, and support products that are specifically intended for cryopreservation systems.
