Standard Configuration

The Janis Model PTSHI-950-LT 1.5 K continuous closed cycle refrigerator cryostat operates continuously from 1.5 K to 300 K (450 K optional) and is a cryogen-free, turnkey alternative to liquid helium. Featuring pushbutton operation including sample temperature adjustment, this top-loading refrigerator can locate samples in either static exchange gas or vacuum, and users can easily change it while the system is operating.

The system offers rapid sample exchange while the refrigerator is operating. The sample is inserted, via a long rod, into a nearly isothermal region of the gas column for cooling. Sample exchange by simply removing the sample rod, switching samples on the rod, and reinserting the rod into the cryostat. The entire sequence takes ~80 min and is performed while the refrigerator is operating.

Capable of achieving 1.5 K in ~9 h, the Janis Model PTSHI-950-LT 1.5 K continuous closed-cycle refrigerator cryostat has a 50.8 mm I.D. sample chamber (optional to 100 mm) and can be designed to customer specifications. The system allows you to cool samples, devices, and/or equipment without the inconvenience and expense of liquid helium.
