What is the meaning of cryostat?
an apparatus for maintaining a constant low temperature
Definition of cryostat : an apparatus for maintaining a constant low temperature especially below 0°C.
What is cryostat in pathology?
Cryostats are used in medicine to cut histological slides. They are usually used in a process called frozen section histology (see Frozen section procedure). The cryostat is essentially an ultrafine “deli-slicer”, called a microtome, placed in a freezer.
Why is a cryostat important?
Cryostats are very important in the field of medicine and other related fields. Their main purpose is to maintain low cryogenic temperatures of human, animal, or plant tissue specimens. Devices can also be mounted within the cryostat machine.

What is the difference between a cryostat and a microtome?
Medical laboratories use a cryostat to preserve frozen tissue samples while a microtome, an extremely sharp cutting instrument mounted inside cryostats, slices the tissue into pieces thin enough to be observed under a microscope. The sliced piece must be so thin as to look nearly transparent.
What are the materials used in cryostat?
Cryostat (Model # CM1900, Leica Microsystems), curved scissors, 1.5-ml Eppendorf tubes, Nonidet P-40 (US Biological, Swampscott, MA), 20 m M Tris (pH 7.4), 150 m M NaCl, 1 m M EDTA, and 4 °C high speed centrifuge (Model # 5415 R, Eppendorf).
How do you control temperature in a cryostat?
Temperature control of the sample within the cryostat is typically performed by controlling the flow rate of cryogen into the cryostat together with a heating wire attached to a PID temperature control loop. The length of time over which cooling may be maintained is dictated by the volume of cryogens available.
