Liquid Nitrogen Cryostat
The Liquid Nitrogen Cryostat developed by Dexing Magnet is a low-temperature thermostat based on the steady-state bubble principle. Liquid nitrogen contains in the liquid nitrogen tank. By adjusting the cone air plug clearance and changing the boiling condition of the gas-liquid interface, the heat leakage of the constant temperature block is approximately stabilized at a certain value. Then the heating power can be adjusted by the temperature control instrument to make the sample seat change the temperature between 65K-800K rapidly and balance exactly on the set temperature.
Performance and characteristics of Liquid Nitrogen Cryostat:
1. Wide temperature range (65K ~ 800K), high efficiency and fast cooling speed;
2. The sample has an ideal stable environment in a vacuum;
3. a low-temperature adsorbent is arranged in the vacuum interlayer, so that the vacuum can be kept for a long time, and the use time of the liquid nitrogen is prolonged;
4. Selection of PT100 Platinum Resistor with good Stability and repeatability for temperature Sensor;
5. A variety of options to meet different test requirements;
6. Convenient use, perfusion and secondary injection of liquid nitrogen; no need for equipment such as pumps and compressors, saving laboratory space, continuous operation of the system without maintenance;
7. The optical sample holder can install the sample quickly. The electrical sample holder has beautiful and easy-to-use wiring terminal;
8. Different sizes, different requirements of liquid nitrogen thermostat can be designed according to customer requirements. (optical, electrical, magnetic, thermal experiments).
