Ultra low temperature freezers (ULT freezers) typically have a temperature range of -45C to -86C and are used for the storage of vaccine，drugs, enzymes, chemicals, viruses, bacteria, cell preparations, and tissue samples, among others. There are several designs for ultra low temperature freezers with varying sizes depending on how much storage is needed and available footprint space.
For frequent use, an upright ULT freezer allows easy access, individual adjustable interior compartments, and fast cooling after opening. A chest ULT freezer gives you safe long-term storage for lesser-used items. Table-top and under-bench ULT freezers are also available. With removable inventory racks, an ultra low temperature freezer can be used to store both freezer boxes and larger items. Look for good temperature control in fluctuating voltage conditions or extreme ambient temperature, and a range of temperature controls from simple manual settings to remote electronic monitoring with alarm systems.
Some types of materials require especially low temperatures. In these instances, you will likely need an ultra-low temperature freezer. These are designed to reach temperatures as low as -85° or -86°, making them an ideal appliance for any facility that requires a consistent temperature to properly store sensitive materials. Ultra low temperature freezers are typically great for consistency and power, but they may also use a lot of energy to maintain those extra low temperatures. This is important to note, as it is possible that you will see a little extra cost when it comes to your energy bill.
