Scryo-S-400 UHV Cryogenic Insert
The Scryo® S-400(abbreviated as S-400) is an ultra-high vacuum compatible cryogenic insert designed for experiments requiring ultra-high vacuum environments such as ARPES, STM, AFM, IR, magneto-optical, ferromagnetic resonance and high-energy physics. It is made of ultra-high vacuum materials and processes to allow for high temperature baking.
The S-400 cryogenic insert transfers liquid helium to the vaporizer of the cryostat for efficient vaporization using an efficient adiabatic transfer piping, which can be used for variable temperature and temperature control in the temperature range of 1.8K-500K. The built-in heater is isolated from the sample space to avoid the effect on the vacuum of the UHV chamber when the heater is working. The S-400 cryogenic insert is characterized by light weight, fast cooling speed, etc. It can be mounted in any direction, with a standard CF35 conflat flange, and other specifications can be optionally added to facilitate the integration with the user-supplied UHV chamber, and the length from the conflat flange to the cold finger can be customized.
The S-400 cryogenic insert offers a wide range of options such as various UHV electrical feedthroughs, 800K high temperature, UHV translation stage, pumped differential rotary stage, tilt stage, and UHV calibrated thermometers, as well as an optional UHV vacuum shroud with optical window.
