Laboratory Freezers
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 temperature-sensitive biological or chemical materials.
Lab freezers are offered as upright vertical, horizontal chest or under-bench units in a range of sizes and capacities. Small, compact benchtop models are ideal for personal use.
A general-purpose laboratory freezer typically stores samples down to -25°C. An ultra-low temperature (ULT) freezer is intended for deep cryogenic storage of samples typically down to -80°C.
Most freezers are built from robust and durable materials such as stainless steel, aluminium, or powder-coated sheet steel.
Laboratory freezers have a selection of internal storage layouts or compartments, some of which may be 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 cryogenic boxes, microplates or cryotubes.
Laboratory freezers come equipped with a range of standard or additional features such as:
- Energy-efficient, microprocessor controlled refrigeration systems
- Digital, user-friendly touchscreen displays
- Lockable, card-entry or self-closing doors for extra safety and sample security
- Spark-free versions for storage of flammable
- Over-temperature audible or visual alarms
- Remote temperature monitoring with USB data download capability
- Inner doors and high-efficiency foam insulation to minimise temperature losses
- Highly efficient pump systems for fast cool-down times
- Fan-assisted forced-air circulating systems to remove moisture and minimise icing
- Automatic gas-powered defrost systems
- CO2 or LN2 safety back-up systems in the event of a power or mechanical failure
