WBL-830Fully automatic surface area and porosity analyzer

WBLSeries of fully automatic surface area and porosity analyzers referenceISO9277、ISO15901International standards andGB-119587According to national standards, based on the principle of static capacity measurement, the adsorption desorption process is tested through mass balance equation, static gas equilibrium, and pressure measurement. The testing process is carried out at liquid nitrogen temperature. After a known amount of gas is filled into the sample tube, it will cause a pressure drop. Therefore, the molar mass of the adsorbed gas at adsorption equilibrium can be calculated. By measuring the equilibrium adsorption capacity, the theoretical model is used to determine the single point and multi-point of the tested sampleBETSpecific surface area,LangmuirSpecific surface area;BJHVolume and area distribution of mesopores and macropores, total pore volume;t―plotMicropore volume and surface area,Dubinin―AstakhovMicroporous distribution,Horvath―KawazoeMicroporous distribution; Density function theory（DFT）And Monte Carlo（MC）Parameters such as aperture distribution model.

Modular pneumatic design

WBLThe series of fully automatic surface area and porosity analyzers introduces the most advanced design concepts in the world today, using a unique modular all stainless steel vacuum gas path design and advanced leak proof and pollution-free measures to ensure the achievement of high vacuum and avoid the disadvantages of easy leakage due to too many connecting pipe joints.

Constant temperature

The independently developed metal Dewar flask, due to its unique internal structure design, can store liquid nitrogen for more than ten days, with almost no loss of liquid nitrogen during the experiment, ensuring a constant temperature of the tested sample while avoiding the defect of fragile and immovable glass Dewar flasks.
