Continuous-Flow Cryostat
-195°C (78 K) to Ambient
This floor-standing cryostat uses a continuous flow of liquid nitrogen from a storage dewar for cooling, and a resistive wire element for heating. The system consists of four separated parts: a cylindrically shaped vacuum chamber, with a liquid nitrogen vessel on top, both integrated into a floor-stand; a temperature control unit; a turbomolecular pump; and a self-pressurized dewar.
