Laboratory Freezers
Laboratory freezers are used to store a variety of samples between −10°C and −30°C, including pharmaceutical, biological, and other commonly used laboratory materials. Products may be upright, freestanding, or under-bench models providing a range of sizes and capacities. An automatic defrost option is available on some products.
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.
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, aluminum, 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:
• 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 materials
• Audio or visual over-temperature alarms
• Remote temperature monitoring with USB data download capability
• Inner doors and high-efficiency foam insulation to minimize temperature losses
• Highly efficient pump systems for fast cool-down times
• Fan-assisted forced-air circulating systems to remove moisture and minimize icing.
• Automatic gas-powered defrost systems
• CO2 or LN2 safety back-up systems in the event of a power or mechanical failure
