JWGB Vapor Series Static-Volumetric Vapor Sorption Analyzer

Adsorbate Such as Carbon monoxide, ammonia and substances that are liquid at room temperature. (Except corrosive/ hyper-toxic/hazardous gas) Vapor sorption temperature 0 - 50 ℃ Pore size distribution range 0.35 - 500 nm

Product Category: Vapour Sorption

Industry: Life Sciences, Membrane Manufacture and Testing, Particle and surface science, Pharmaceutical, Personal Care and Natural Products

Supplier: JWGB

Description

Preparation of adsorbate by evaporator.
Use stainless steel and thermostatic control module as manifold. Constant temperature range: room temperature to 50 oC.
Effective cold trap system prevents vapor from polluting vacuum pump and environment.
FFKM (Perfluoroelastomer) O rings for banner sealing performance.
Applications
Measurements of BET surface area and pore size distribution.
Measurements of various gas and steam adsorption isotherms.
Testing of isosteric heat of adsorption.
Determination of selective adsorption coefficient.
