CRYOGENIC / LOW-TEMPERATURE LAB EQUIPMENT

Leybold RDK 10-320 Closed-Cycle Helium Cryostat Cold Head

Model RDK 10-320  |  Catalog no. 891 11  |  Serial A83100012

Exceptionally clean Leybold RDK 10-320 closed-cycle helium cryostat / cold-head base assembly acquired from Arizona State University laboratory surplus. The unit is marked Basiseinheit 210 and bears a Cool Pair Plus reconditioning label. A compatible helium compressor and temperature-control system were not available for testing, so full cryogenic performance is unverified.

Equipment overview

The Leybold RDK 10-320 is a two-stage closed-cycle helium cryostat / cold head for low-temperature laboratory research. Published RDK 10-320 installations use a Gifford-McMahon refrigeration cycle and, with the appropriate compressor and temperature controller, operate over approximately 10 K to 320 K. This unit is marked Basiseinheit 210, Kat.-Nr. 891 11, and includes the installed cold finger, pressure gauge, and helium connections shown. It is offered as the pictured cold-head/base assembly only and has not been cryogenically performance-tested by us.

Condition: Used — exceptionally clean, untested

Assessed on four axes before listing.
