Oxford Cryosystems

Oxford Cryosystems is a market leading manufacturer of low temperature devices. The company made history designing the first open-stream cooler, the Cryostream (80-500 K), which quickly became the system of choice for sample cooling.

Its product range has since expanded to include cryogen-free systems such as the Cobra (80-500 K) and N-Helix (28-300 K), alongside a specially adapted system for powder diffraction, the PheniX (12-290 K). The variable-speed Gifford-McMahon coldheads housed in these products are also available separately, operating at speeds of 40-90 rpm.

The company’s single-stage coldhead range includes the 0/12 and 0/40, respectively delivery cooling powers of 12 and 40 W at 77 K. The two-stage coldhead range includes the 2/9 and 6/30 models, some of the smallest GM coldheads available, both delivering base temperatures of 10 K.

Alongside Oxford Cryosystems’ K450 Helium Compressor, these devices are used in a wide range of applications, from superconducting magnets to radio astronomy.
