Full-automatic Filter Membrane Pore Size Analyzer

The membrane pore size analyzer precisely measures parameters such as bubble point pressure, maximum pore size, mean pore size, most probable pore size, and gas permeability for various microfiltration membrane materials. It visually presents pore size distribution via charts, detects sample defects, and estimates filtration precision.

Applications

It can determine the pore size distribution of a wide range of filtration materials—including filter paper, fuel cell carbon paper, metal felt, metal mesh, porous ceramics, polymer membranes, non-woven fabrics, asbestos cloth, and sintered glass—with fully automated testing and data acquisition.

Test Methods

Bubble pressure method (also known as the capillary flow method or gas-liquid displacement method), liquid-liquid displacement method.
