Dipstick Cryostats are simple cryogenic cooling devices designed to be immersed directly into a liquid cryogen, such as liquid helium or liquid nitrogen, to achieve and maintain low temperatures. They provide a convenient way to cool samples quickly without the need for complex refrigeration systems.
These cryostats are widely used in low-temperature physics, superconductivity studies, and materials science experiments where straightforward cooling is sufficient. Key advantages include ease of use, portability, relatively low cost, and compatibility with magnetic and optical measurement setups, though they require a continuous cryogen supply.
