Cryocooler System utilizes recirculating helium gas.
Electronic Components & Devices

Cryocooler System utilizes recirculating helium gas.

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...

Sample Vacuum Chamber enables safe transfer to probe station.

Miniature, transportable sample vacuum chamber can be used for transferring wafer/substrates under vacuum from glove box with special environment into vacuum or cryogenic micro-manipulated probe station (or into vacuum chamber) and back into glove box after testing, measurements, or preparations. Without requiring gate valves, product protects wafer/substrates from atmospheric contamination both...
