RMC-Cryosystems 1/4 watt, 4.2 K closed cycle refrigerator with cold head module LTS-1C-4.2CH

RMC closed cycle refrigerator on sale from Franklin & Marshall College.

$ Cost to Crate and Ship This is a CTI-Cryogenics cold head (we believe Model 350C), with a Joule-Thompson expansion valve 3rd stage added by RMC. This 3rd stage gets its high-pressure helium gas flow from the supply line for the cold head, but requires its own pumped return line using the same standard connection fittings and an additional stage of compression. Includes an RMC 4000 temperature controller. The compressor module leaks. Offered AS IS for free. You pay to crate it and ship it.
