STV-80 liquid nitrogen storage cryothermostat comes with 0.4L liquid nitrogen storage space, liquid nitrogen can be easily filled through the liquid nitrogen refill port on the top, and the refill of liquid nitrogen will not affect the temperature control of the system。The thermostat has a liquid nitrogen flow control lever, which can be used to adjust the cooling capacity of the thermostat。The built-in heater and sensor cooperate with the external temperature control instrument to achieve the temperature change and control of the low temperature thermostat。The STV-80 liquid nitrogen storage cryothermostat provides continuous temperature change from 65K to 800K, providing great convenience for scientific experiments requiring both low and high temperatures。

  The sample chamber is designed with quick-discharge clamp, which is convenient to open the sample chamber quickly when the sample needs to be changed。In order to meet the electrical testing needs of customers, the cryothermostat can be configured with various electrical leads (such as Ph-Br wire, coaxial cable and tricoaxial cable, etc., resistance sample holder or probe sample holder) according to the experimental needs.。The thermostat is equipped with four transparent fused quartz Windows with transmission wavelengths ranging from ultraviolet to near-infrared, and other window materials can be selected to meet the wide spectrum range of tests from far/mid-infrared, ultraviolet to X-ray。
