The XR AirJet Sample Cooler, available in -80C or -40C configurations provides sample temperature control for NMR, EPR and X-Ray diffraction using a mechanically refrigerated, temperature controlled air stream. House compressed air is utilized for the air stream and no expendable refrigerants are required. When dry air passes through the AirJet it is cooled by the mechanical refrigeration system and provides a precise regulation of heat input to control the temperature of the air stream.

This design approach creates a temperature stability of +/- 0.1C. Longer delivery lines allow the positioning of the refrigeration system at a greater distance from your sample area, particularly important for NMR applications.
