Patent

Patent name: physical adsorption instrument with a constant device with liquid nitrogen surface

Protective point:

a. Automatically add the system through liquid nitrogen to achieve constant liquid nitrogen surfaces, fundamentally eliminating the error of the introduction of changes in the warm zone;

b. High -precision acquisition structure of liquid nitrogen surface;

c. Electric turbine -type liquid nitrogen automatic pump into the structure, high accuracy of the constant control of the liquid surface;

d. Prevent the safety structure of frozen blocking;

e. The constant structure of the liquid nitrogen surface can be quickly installed and disassembled. After disassembly, it has no effect on the original function;
