Lake Shore Janis SuperTran-VP Continuous Flow Cryostats
SuperTran-VP Cryostat Systems
Lake Shore SuperTran-VP cryostats cool samples by immersion in a temperature-controlled flowing gas. Simple to operate, they use a high-efficiency transfer line to deliver LHe (or LN2) to the sample chamber for cooling the sample from <2 K to 325 K (or 77 K to 325 K with LN2). Built-in heaters and sensors provide precision dual-loop variable temperature capability. Temperatures below 4.2 K are achieved by reducing the venting helium gas pressure using a mechanical vacuum pump.
Typical applications include spectroscopy (photoluminescence, FTIR, UV-visible, Raman), materials characterisation (resistivity, Hall effect), as well as low-temperature and component testing.
These continuous flow cryostats offer quick sample cool down, compact designs and maximum LHe efficiency.
FEATURES
- 1.5 K to 325 K
- Can use either LHe or LN2
- Sample-in-flowing-vapour
