Ultra-low Temperature Freezers: How to Choose the Right One
Ultra-Low Temperature Freezers
Ultra-low temperature freezers are ultra-cold laboratories that operate at extremely low temperatures. With a temperature range of -45°C to -86°C, Yatherm Scientific offers ultra-low temperature freezers that are suitable for storing drugs, enzymes, chemicals, bacteria, and other samples.
Ultra-low temperature freezers are available in a variety of designs and sizes,
depending on the amount of space required. The upright freezer and the chest
freezer are the two most common types. ULT upright freezers provide quick and
easy access to frequently used items, while ULT chest freezers are designed to
store items that are less frequently used for long periods of time. Most
laboratories use upright freezers to save space and make layouts more
convenient.

storage volume at ultra-low temperatures
There
is a wide range of internal storage capacities available for ultra-low
temperature freezers, ranging from 200 litres to a maximum of 800 liters. In
order to maintain the temperature as uniform as possible, it usually consists
of shelves on the inside on which the research samples are placed and each
shelf is enclosed by an internal door.

What is
the operation of an ultra-low temperature freezer?
A
freezer that operates at ultra-low temperatures may consist of one high-power
compressor that is hermetically sealed or two cascade compressors.
Laboratory
ULT freezer systems typically use air-cooled condensers. This type of battery
is made up of tubular batteries (copper or copper-aluminum) arranged in a way
that allows maximum heat transfer from the surface to the battery. An
engine-driven fan circulates the cooling air, and capillary tubes are used to
expand the refrigerant fluids.
The
evaporation process is carried out by steel plate heat exchangers located
inside the chamber, or by coils. As opposed to freezers with coils in the
insulation cavity, the coil in the cabinet provides greater efficiency in heat
exchange.
Uses of
ultra-low temperature freezers
There
are many applications in ultra-low temperature freezers...
Storage
of biological and biotech materials in research universities, hospitals, blood
banks, and forensic labs.
