Ultra-Low Temperature Freezers
ULT Ultra-Low Temperature laboratory freezers, also known as minus eighty freezers, are a specialised category of laboratory freezer intended for the deep cryogenic storage of samples, typically down to -80°C.
ULT Laboratory freezers are essential items of equipment in many laboratories, especially those that require the safe and secure short-term or long-term frozen storage of materials such as vaccines, or temperature-sensitive biological samples including DNA, RNA, virus or proteins.
ULT freezers are offered as vertical units, horizontal chest units, or under-bench units in a range of sizes and capacities of up to 900L or more. Small, compact portable benchtop models, typically 25L, are also available and are ideal for personal use.
Most ULT freezers are built from robust and durable materials such as stainless steel, aluminium, or powder-coated sheet steel.
ULT freezers have a selection of internal storage layouts or compartments, often reconfigurable by the user. For example, they may have combinations of adjustable and exchangeable doors, shelves, baskets, trays or special racking systems designed for the storage of a wide range of refrigerator and freezer accessories, including cryogenic boxes, vial storage systems or cryotubes.
Many ULT freezers come equipped with a range of features such as:
- Energy-efficient, microprocessor-controlled freezing systems
- Digital, user-friendly touchscreen displays
- Lockable, card-entry or self-closing doors for sample security
- Over-temperature alarms
- Remote temperature monitoring with USB downloads
- Inner doors and high-efficiency foam insulation to minimise temperature losses
- Highly efficient pump systems for fast cool-down times
- Safety back-up systems in the event of a power or mechanical failure
