A cryostat (from cryo meaning cold and stat meaning stable) is a device used to maintain low cryogenic temperatures of samples or devices mounted within the cryostat. Low temperatures may be maintained within a cryostat by using various refrigeration methods, most commonly using cryogenic fluid bath such as liquid helium . [ 1 ]
Technically, cryomicroscopy implies compatibility between a cryostat and a microscope. Most cryostats make use of a cryogenic fluid such as liquid helium or liquid nitrogen. There exists two common motivations for performing a cryomicroscopy. One is to improve upon the process of performing a standard microscopy.
Frozen section procedure: tissue embedded in optimal cutting temperature compound, mounted on a chuck in a cryostat and ready for section production. Optimal cutting temperature (OCT) compound is used to embed tissue samples prior to frozen sectioning on a microtome-cryostat. This process is undertaken so as to mount slices (sections) of a ...
However, dry cryostats have high energy requirements and are subject to mechanical vibrations, such as those produced by pulse tube refrigerators. The first experimental machines were built in the 1990s, when (commercial) cryocoolers became available, capable of reaching a temperature lower than that of liquid helium and having sufficient ...

Tissue embedded within optimal cutting temperature compound (OCT), mounted on a chuck in a cryostat, and ready for section production. The frozen section procedure is a pathological laboratory procedure to perform rapid microscopic analysis of a specimen. It is used most often in oncological surgery. [1] The technical name for this procedure is ...
In this clever way it is avoided that the heat, released at the hot end of the second tube, is a load on the first stage. In applications the first stage also operates as a temperature-anchoring platform for e.g. shield cooling of superconducting-magnet cryostats. Matsubara and Gao were the first to cool below 4 K with a three-stage PTR. [21]
