Characteristic structure:

Technical advantages:

a. High throughput and efficiency: support analysis of up to 12 samples at a time;

b. Real full automation: the internationally initiated degassing furnace and Dewar cup can be switched automatically without manual transfer of sample tubes or degassing furnace;

Patent name: Full automatic physical adsorption instrument with automatic position switching between heating furnace and thermostatic bath cup

Patent No.: ZL20220232044.8;

c. High time utilization rate: It solves the problem of time waste when conventional instruments can not enter the test after degassing is completed after work, making it a reality to load samples after work and look at data at work;

d. Thoroughly eliminate "helium pollution": helium test dead volume → vacuum heating degassing → adsorption test is the first internationally to solve the helium pollution problem of micropore analysis and improve the test accuracy;

e. Anti flying degassing: support "program pressure control"+"program temperature control" degassing, and automatically lift the degassing furnace according to the pressure change, which will prevent the sample from flying;

Patent name: Physical adsorber with programmed pressure control anti flying degassing system
