Cryostat
Cryostat
A Cryostat (pronounced: /ˈkraɪ.əˌstæt/) is a device used to maintain low cryogenic temperatures of samples or devices mounted within it.
Etymology
The term "Cryostat" comes from the Greek words "kryos" meaning cold and "statos" meaning stable, stationary or standing.
Description
Cryostats have a wide range of applications within science, particularly in the fields of materials science, physics, and biology. They are used to cool and maintain the temperature of an object at a very low level, often close to absolute zero, which is -273.15 degrees Celsius or -459.67 degrees Fahrenheit.
Cryostats are essential in medical laboratories for the preparation of tissue samples. In histopathology, a branch of pathology, they are used to rapidly freeze tissue specimens to create frozen sections for immediate examination under a microscope.
Types of Cryostats
There are several types of cryostats including the continuous flow cryostat, the closed cycle cryostat, and the bath cryostat. Each type has its own specific uses and advantages depending on the application.
