Janis Recirculating Gas Coolers
Continuous Closed Cycle Refrigerator Cryostat
Ultra-stable cryogenic microscopy platform
The SuperTran product line has long been an industry standard for continuous-flow cryogenic systems. With the addition of an RGC4 Series recirculating gas cooler, these cryostats can be cooled without the need for liquid cryogens.
A closed loop of helium gas is cooled by a cryocooler, and the cold helium gas travels to the cryostat through a flexible vacuum-insulated transfer line. The gas cools the sample mount and thermal radiation shield before returning to the cryocooler for continuous recirculation. Samples can be changed without warming up the RGC4, allowing fast turnaround times. When paired with a Lake Shore Cryotronics ST-500 cryostat, the combination is an ultra-stable cryogenic microscopy platform, cooling samples and devices to below 4 K without the use of liquid helium.
A cryogen-free option for continuous flow cryostats
Typical applications include micro-PL, micro-Raman, and high spacial resolution imaging.
