Cryogen-free: run an LHe cryostat without the LHe
With the addition of a recirculating gas cooler (RGC), LHe cryostats can be cooled without the need for liquid cryogens.
The RGC runs helium in a closed loop, making a continuous flow cryostat cryogen-free. Helium gas is cooled and liquefied by the RGC’s cryocooler and travels to the cryostat through a flexible vacuum-insulated transfer line. LHe cools the sample.
The RGC captures the evaporated gas through the transfer line and reliquefies it, continuously recirculating the helium.
The RGC is compatible with Lake Shore ST and STVP cryostats and can be used with LHe cryostats from other vendors as well.
