|Item:||Advanced Capillary Flow Porometer||Pore Size:||0.02-500μm|
|Test Method:||Bubble Pressure Method|
GL-2000PB Advanced Capillary Flow Porometer is an instrument produced by one Beijing research center, used to measure pore size, pore size distribution, gas permeability and other related parameters of the materials with through pore by relying on liquid displacement technology (i.e. bubble pressure principle).
This Capillary Flow Porometer uses infiltrate liquid and gas as the carrier, and is more pollution -free, safer and more convenient compared with mercury intrusion method.
In addition, it conform with ASTM F316 - 03(2011) standard Test Methods for Pore Size Characteristics of Membrane Filters by Bubble Point and Mean Flow Pore Test.
Through hole test of filter membrane, fiber membranes, battery diaphragm, fabric, non-woven fabrics, paper, filter element, ceramics, cemented metals, rock, concrete and other materials.
