Liquid Nitrogen Variable Temperature Test Dewar is conveniently filled with liquid nitrogen, variable temperature and temperature control are realized through thermal impedance displacer, built-in heater and temperature controller, with working temperature range of 77K-350K.

Second, the quick release connection is easy to quickly open the sample chamber, can be configured with a variety of electrical leads (such as phosphor bronze cryogenic wire, coaxial cable and tri-coaxial cable, etc.). Two transparent fused silica windows are standard, and other windows can be selected according to the transmission wavelength range to meet the wide spectral range of testing from far/mid infrared, ultraviolet to X-ray. iii.

Typical applications include spectroscopic testing (PL spectroscopy, FTIR and UV-Visible), electrical testing (conductivity, Hall effect) as well as cryogenic imaging, microscopy and component testing.

Lightweight and cost-effective, they are the ideal multi-purpose laboratory thermostats. In addition users can customize it for different testing requirements.
