Ultra Low Temperature Cryostats

High Precision Devices, Inc. (HPD) is the world leader in Adiabatic Demagnetization Refrigerator (ADR) cryostats, offering test platforms regulated at 100 mK. HPD also builds Dilution Refrigerator (DR) cryostats, both cryogen-free (dry) systems and liquid cryogen systems. Our cryostats employ modular design offering the maximum flexibility for service and experimental adjustment. HPD cryostats are functional and feature rich and also lend themselves to fully customized designs.
