Filter Membrane Pore Analysis Tester
The Filter Membrane Pore Analysis Tester is a precision instrument designed to measure the pore size, distribution, and integrity of flat filter membranes. Utilizing the principle of capillary flow porometry, the tester provides quantitative data on bubble point, mean flow pore size, and full pore size distribution. This information is critical for evaluating filtration efficiency, flow rate, and retention performance of membranes used in microfiltration, ultrafiltration, and sterile filtration applications.
Application
(1) Determining pore size distribution, bubble point, and mean flow pore size of flat filter membranes.
(2) Quality control in the production of filtration membranes to ensure consistency and compliance with specifications.
(3) Research and development of new membrane materials and designs.
(4) Characterization of membranes for various filtration applications, including water purification, pharmaceutical, food & beverage, and chemical processes.
(5) Investigating performance issues in membranes, such as defects, irregular pore sizes, or compromised integrity.
(6) Validation of membrane integrity and performance for sterilization and critical filtration processes.
Standards
(1) ASTM E1294 — Standard Test Method for Pore Size Characteristics of Membranes by Bubble Point and Mean Flow Pore Test
(2) ASTM F316 — Standard Test Method for Pore Size Characteristics of Membrane Filters by Capillary Flow Porometry
(3) ISO 4003 — Determination of Pore Size and Bubble Point of Membranes
(4) ISO 15901-2 — Pore size distribution and porosity analysis of materials using capillary flow methods
(5) USP <788> — Particulate Matter in Injections (relevance for sterile filtration membrane validation)
(6) EN 14683 — Medical face masks: bacterial filtration performance (membrane evaluation)
