STG-80-V liquid nitrogen storage cryostat comes with 1.4L liquid nitrogen storage space, liquid nitrogen can be easily filled through the liquid nitrogen replenishment port at the top, replenishment of liquid nitrogen will not affect the temperature control of the system. The thermostat is equipped with a liquid nitrogen flow regulating valve, which can be used to regulate the cooling capacity of the thermostat. The built-in heaters and sensors work together with the external thermostat to achieve the variable temperature and temperature control of the cryostat.STG-80-V Liquid Nitrogen Storage Cryostat can provide continuous temperature change from 78K to 500K, which is very convenient for cryogenic scientific experiments.

  The STG-80-V is designed with a top loading and unloading sample rod, which allows for quick sample changes without having to return the entire system to room temperature when a sample change is required. The sample chamber is completely cooled in the atmosphere for more uniform cooling, making it easy to cool samples that are not easily cooled, such as liquids and powders. In order to meet the electrical testing needs of customers, the cryostat can be equipped with a variety of electrical leads (e.g. Ph-Br, coaxial and triaxial cables, etc.), resistor holders or probe holders according to the experimental needs. The thermostat comes standard with a four-way transparent fused silica window, transmitting wavelengths from UV to NIR, with other optional window materials to meet a wide spectral range of tests from far/medium infrared, UV to X-rays, and the ability to be filled with liquid nitrogen without interfering with the test.
