Schoonover Inc.

Cryocoolers (or Cryostats)

ColdEdge Custom Laboratory Cryostats (also known as Cryostats)

Cryocooler –  Low Temperature Sample Cooling to 1.7K

Cryogen free sample cooling using a laboratory cryocooler (also know as a cryostat) can be  either closed cycle cryogenic coolers (cryogen free) , open cycle cryogenic coolers, liquid helium transfer lines and many customer specific cryo-refrigerator systems that operate in the 1.7K to 1000K temperature range.

Schoonover works with designs using Sumitomo (and other coldhead manufacturers) cryocoolers and Coldedge Technologies interfaces to provide cryogen free laboratory cryocoolers. Open cycle systems can also be provided even through popularity of open cycle systems are declining because of helium   availability. Ask us for a cryogen free quotation to replace your open cycle cryocooler.

Taking advantage in the choice of cryo-cooler manufacturers, we can match the best performing cold head for the customer application.

We supply complete systems with application specific and/or custom vacuum chambers , radiation shields, sample holders, windows, temperature sensors, heaters, wire leads for experiments  and feed-throughs (UHV, SMA, coax & other), temperature controllers, vacuum pump systems, and sample manipulation attachments.

Options include low vibration interfaces and heaters for heating the sample to 1000 deg. C.

Custom cryo-cooler projects are welcome. Our engineering staff has many years experience in designing cryogenic research projects.

All Cryo-Cooler (Cryostat) Systems are assembled and completely tested prior to shipment and detailed performance test data is generated and supplied to our customers.  The cooler is also tested with no load  and interface (before installing the interface) and this information is also supplied with every shipment.
