The Chimera is the new variable temperature chamber for flat plate powder samples from Oxford Cryosystems, with a temperature range of 70- 525 K, and excellent stability of 0.1 K. Unlike traditional cooling and heater chambers, the Chimera works by incorporating an Oxford Cryosystems single stage GM cooler, meaning that no liquid nitrogen is required.

For further information on integration of the Chimera with your powder diffractometer, we recommend you speak to the relevant X-ray company or contact us for further details.
