STG-80-S liquid nitrogen storage cryothermostat comes with 1.4L 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 valve, 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。STG-80-S liquid nitrogen storage cryostat can provide continuous temperature change from 78K to 500K, which provides great convenience for low temperature scientific experiments。

  The STG-80-S features a top-loading sample rod design that allows for quick sample changes without bringing the entire system back to room temperature when a sample needs to be changed。The sample chamber is completely in the atmosphere to cool more evenly, convenient to cool liquid, powder and other samples that are not easy to cool。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 from far/mid-infrared, ultraviolet to X-ray testing, and can fill liquid nitrogen without affecting the test。

System features:

• Wide temperature range: from 78 K to 325 K
• The sample is in the atmosphere, which can fully cool the sample in hot contact with powder or liquid
