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 characterization (resistivity, Hall effect), as well as low-temperature and component testing.
