All stainless steel gas system, stainless steel pipe, fittings, using hardwired VCR, stainless steel sample tube, the maximum system pressure 30MPa;

Dead zone volume and temperature tests

With 99.999% high purity HE; having mad HE volume test function; with automatic process control HE hot zone temperature zone test function; achieve higher accuracy;

Sample tube

Standard stainless steel sample tube 10ml; 10ml quartz sample tube; large volume sample tube Optional;

Independent P0

Independent saturated vapor pressure (P0) test stations, to ensure high accuracy low temperature adsorption test;；

Pre-treatment

2-way degassing station has individual climate control, and an independent timing, sample degassing treatment can support and test carried out simultaneously at different temperatures and at different times;
Having a "normal heating vacuum molecular diffusion mode" and "molecular replacement mode" in two optional features; sample preparation method of molecular replacement static mode molecular diffusion model efficiency by more than 1 times, can save more than half of the pretreatment time, solve the problems of problem a long time;

Anti-pumping fly

Dust pollution vortex principle hardware original equipment, in combination with software anti-fly program drawn eliminate volatile samples at high vacuum elutriation boiling, thus avoiding the contamination volatiles pipeline valves.

Level Control

Liquid nitrogen to keep the original surface servo system, the elimination of the testing process because the liquid nitrogen so that nitrogen volatilization surface changes brought dead volume change, improve test accuracy;
