Ultra Low Temperature Freezers
Have you ever wondered about the main uses for ultra-low-temperature freezers?
What is an ultra low temperature freezer?
An ultra-low temperature freezer, also known as a ULT freezer, typically has a temperature range of -45°C to -86°C and is used for the storage of drugs, enzymes, chemicals, bacteria and other samples.
Low temperature freezers are available in various designs and sizes depending on how much storage is needed. There are generally two versions, an upright freezer or a chest freezer with access from the upper part. An upright ultra low freezer gives easy access for frequent use and a chest ultra low freezer freezer allows for long-term storage of less frequently used items. The most common type is the upright freezer as laboratories are frequently looking to save space and make layouts more accessible.
The internal storage volume of an ultra low temperature freezer can generally start from an internal capacity of 200 litres up to a maximum capacity of 800 litres. It typically has shelves on the inside where research samples are placed and each shelf is closed by an internal door in order to maintain the temperature as uniform as possible.
How does an ultra low temperature freezer work?
An ultra low freezer can be a single high-power compressor hermetically sealed or two cascade compressors. The two cascade solution, is two refrigeration circuits connected so that the evaporator of one cools the condenser of the other, facilitating the condensation of the compressed gas in the first circuit.
