Cryocooler is the only thing included in purchase: wiring harness, variac, and temperature meter are not included in sale (if you need them, reach out and we can sell them to you separately). Do not over-drive the coolers or damage may result.

In our check it ran normally and pulled down to cryogenic temps; this platform is built to hold a cold stage in the liquid-nitrogen regime (~77 K class) for long-duration operation. Typical use cases: cooling HTS\/superconducting RF filter assemblies (these units were famously used in SuperLink-style cryo filter cans), building a compact cryostat cold finger for detectors\/low-noise electronics, and general cold-trap\/cryopumping duties in a vacuum system (water vapor cleanup, condensables, gas capture experiments). Practical integration notes: it’s a helium closed-cycle cooler that has a resonance frequency right around 60 Hz, and the warm end needs serious heat rejection (good forced air; some people add a water jacket).\u003c\/p\u003e\u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0;\"\u003e\u003cbr\u003e\u003c\/p\u003e \u003cbr\u003e \u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0;\"\u003eZV\u003c\/p\u003e","brand":"Lab Liquidators Store","offers":[{"title":"Default Title","offer_id":52055821091108,"sku":"SP111116849","price":3950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/5289\/2964\/files\/406726578537-0.jpg?v=1772296750","url":"https:\/\/store.labliquidators.com\/products\/tested-superconductor-technologies-hybrid-98-sterling-cryogenic-cooler-cryocool","provider":"Lab Liquidators Store","version":"1.0","type":"link"}
