Dry Systems

The Proteox™ Family

Dry systems do not require the use of cryogenic liquids to provide the 4 K environment. Instead, pulse tube refrigerators are used. These enable push-button operation, can reduce the cost of ownership, and negate the need for a helium liquefier

Our Oxford Instruments Cryofree® (cryogen free) range of products provides the user with much more experimental space and a larger sample plate, due to not needing a dewar surrounding the system containing the liquid helium for cooling. Mechanical vibrations from the pulse tube refrigerator are significantly reduced using a comprehensive range of vibration isolation techniques.

The compact Cryofree® ProteoxS dilution refrigerator delivers faster turnaround in a smaller size, with no compromise on performance.
