Avantgarde STG-80-V Liquid Nitrogen Storage Cryostat comes with 1.4L of liquid nitrogen storage space, the liquid nitrogen can be easily filled through the liquid nitrogen refill port on the top of the thermostat, and the refill 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 heater and sensor work together with the external thermostat to realize the variable temperature and temperature control of the cryostat.The 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 sample changes are required. The sample chamber is completely cooled in the atmosphere for more uniform cooling, making it easy to cool samples such as liquids and powders that are not easily cooled. In order to meet the electrical testing needs of customers, the cryostat can be configured according to the experimental needs of a variety of electrical leads (such as Ph-Br wire, coaxial cable and tri-coaxial cable, etc.), resistor sample holders or probe sample holders. The thermostat comes standard with a four-way transparent fused silica window, transmitting wavelengths ranging 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 is capable of filling liquid nitrogen without affecting the test.

System Features:

- Wide temperature range: from 78 K to 325 K
- Sample in atmosphere for adequate cooling of samples in thermal contact such as powders or liquids
- Large sample space with a variety of sample holders for testing a wide range of films, blocks, powders and liquids.
- 1.4L of liquid nitrogen storage space, cold holding time of up to 6 hours, can be filled with liquid nitrogen without affecting the experiments
- 4 optical windows (38mm) as standard.
- Equipped with temperature control system
- Support standard optical sample holders, powder sample holders, liquid sample holders, resistance sample holders, probe sample holders and resistance sample holders, a variety of sample holders to choose from.
- Liquid Nitrogen Flow Control Valve to regulate thermostat cooling capacity.
- Sample chamber is designed with a top-loading sample bar for easy sample changeover
- Compact size for easy integration into commercial spectrometer equipment
