TOP-200 Extensible multi-stations gas adsorption analyzer

Outline

TOP-200 Extensible multi-stations gas adsorption analyzer

AMI has re-incorporated many of the technical advantages of the adsorption field and launch the TOP-200 Extensible multi-stations gas adsorption analyzer. TOP-200 gas adsorption analyzer is compact and powerful, and can accurately test micropores, mesopores and surface area to study the adsorption behavior of different adsorbates at different temperatures.


TOP series of instruments have a completely new internal structure, enabling the full independence of different analysis stations. At the same time, four analysis stations can complete four different gas adsorption experiments. The four stations can start the experiment separately and complete the experiment independently without waiting for each other.
