MEMBRANE AND FILTER CHARACTERISATION TECHNIQUES AVAILABLE FROM POROMETER
CAPILLARY FLOW POROMETRY
The principle of measurement is the displacement of a wetting liquid from the pores of the samples by applying gas pressure. Our instruments are widely used to measure porosity, minimum, maximum (or first bubble point) and mean flow pore sizes, and pore size distribution of through pores in membranes, nonwovens, papers, filtration and ultra filtration media, hollow fibres and ceramics with improved accuracy and reproducibility compared to other equipment in the market.
Gas/liquid porometry based on pressure scan: a single valve is opened during a measurement and the pressure and the resulting gas flow are measured continuously.
Gas/liquid porometry based on pressure/step stability: the porometer detects when a pore empties at a certain pressure and waits until all pores of the same diameter have been completely emptied before accepting a data point. Specially indicated for samples with a complex pore structure.
