STV-80 liquid nitrogen storage cryostat comes with 0.4L 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 adjustment lever, 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.STV-80 Liquid Nitrogen Storage Cryostat can provide continuous variable temperature from 65K to 800K, which is very convenient for the scientific experiments that need both low temperature and high temperature.

  The sample chamber is designed with quick-release clamps, which facilitates the quick opening of the chamber when the sample needs to be replaced. In order to meet customers' electrical testing needs, the cryostat can be configured with a variety of electrical leads (e.g., Ph-Br wires, coaxial and tri-coaxial cables, etc., resistor holders or probe holders) according to experimental needs. The thermostat comes standard with a four-way transparent fused silica window, transmitting wavelengths from UV to NIR, and other window materials are available as options to satisfy a wide spectral range of tests from the far/mid infrared, UV to X-ray.
