2. Cryostat - Wikipedia

   en.wikipedia.org/wiki/Cryostat

   The cryostat is essentially an ultrafine "deli-slicer", called a microtome, placed in a freezer. The cryostat is usually a stationary upright freezer, with an external wheel for rotating the microtome. The temperature can be varied, depending on the tissue being cut usually from −20 °C to −30 °C.

3. Frozen section procedure - Wikipedia

   en.wikipedia.org/wiki/Frozen_section_procedure

   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 ...

4. Dilution refrigerator - Wikipedia

   en.wikipedia.org/wiki/Dilution_refrigerator

   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 ...

5. Optimal cutting temperature compound - Wikipedia

   en.wikipedia.org/wiki/Optimal_cutting...

   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 compound (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 ...

6. Microtome - Wikipedia

   en.wikipedia.org/wiki/Microtome

   Frozen section procedure: water-rich tissues are hardened by freezing and cut in the frozen state with a freezing microtome or microtome-cryostat; sections are stained and examined with a light microscope. This technique is much faster than traditional histology (5 minutes vs 16 hours) and is used in conjunction with medical procedures to ...

7. Cryocooler - Wikipedia

   en.wikipedia.org/wiki/Cryocooler

   A refrigerator designed to reach cryogenic temperatures (below 120 K, -153 °C, -243.4 °F) is often called a cryocooler.The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW.
