Featuring cryogen-free, closed-cycle design, Cryocooler System uses recirculating helium gas as direct replacement for liquid helium to cool continuous flow cryostats. Pulse tube-cooled and Gifford-McMahon cryocooler options are available in various capacities and base temperatures. After passing through heat exchangers on cryocooler, helium gas flows through vacuum insulated transfer line into cryostat. Gas cools sample and is then returned to cryocooler for re-cooling and continued circulation.
