The Convergence Inspector Bubble Point (BP) tester automatically determines the BP and mean flow pore size of membranes and filters according to the ISO4003 and ASTM F316-03 standards. The unit automatically wets the inserted sample and determines the bubble point by applying a pressure slope on the filter. When air breakthrough occurs a pressure drop and increase in gas flow is detected and the measurement is stopped.
The easy-to-use touchscreen interface allows you to quickly set up automated experiments. The system is ideal for quality control and characterization of membranes.
The system is highly customizeable and can for example be designed to support several filter holders, house a built-in air compressor if pressurized air is not available or inlcude a liquid flowmeter to perform experiments determining the clean water flux.
