Liquid Nitrogen Cryostat
Dexinmag Liquid Nitrogen Cryostat has the advantages of wide temperature range(65K~800K), high efficiency, fast cooling speed, stable environment, and many options. It has become the preferred low-temperature acquisition equipment for many scientific research experiments.
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.
Main features: high cost-effectiveness, compact structure, no consumption of refrigerants, strong expansibility.
Performance and characteristics of Liquid Nitrogen Cryostat:
-
Wide temperature range (65K ~ 800K), high efficiency and fast cooling speed;
-
The sample has an ideal stable environment in a vacuum;
-
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;
-
Selection of PT100 Platinum Resistor with good Stability and repeatability for temperature Sensor;
-
A variety of options to meet different test requirements;
-
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;
-
The optical sample holder can install the sample quickly. The electrical sample holder has beautiful and easy-to-use wiring terminal;
-
Different sizes, different requirements of liquid nitrogen thermostat can be designed according to customer requirements. (optical, electrical, magnetic, thermal experiments).
