Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Filtration And Membranes. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This microporous filter medium is made from modified polyethersulfone (PES) and supplied with a white, plain surface. It is hydrophilic as standard;a hydrophobic version is stated to be available on request.
Listed configurations include membrane discs in multiple diameters and sheet material in 260, 270, or 420 mm widths. Nominal pore-size options are 0.1, 0.22, 0.45, 0.65, 0.8, 1.2, and 3.0 μm, while the listed membrane thickness is 110–140 μm. The stated uses include air, liquid, powder, and solid filtration.
The membrane is also described for biological, analytical, electronic, pharmaceutical, beverage, and sterilizing filtration applications. For process assessment, the listed pH range is 1–14. Maximum forward operating pressure is stated as 4.2 bar at 23°C and 1.5 bar at 85°C.
Performance figures are provided for selected grades under specified test conditions. The 0.22 μm membrane has a listed flow rate of at least 15 mL/min/cm² at 1 bar and a water bubble point of at least 3500 mbar at 23°C.
The 0.45 μm membrane has a listed flow rate of at least 35 mL/min/cm² at 1 bar and a water bubble point of at least 2500 mbar at 23°C. These figures should be evaluated under the buyer’s actual fluid, temperature, pressure, housing, and sterilization conditions.
Before procurement, confirm the required pore size, disc diameter or roll width, quantity, hydrophilic or hydrophobic configuration, and whether the membrane will be supplied alone or incorporated into a filter element.
Buyers should also request current technical documentation for the exact grade, including chemical compatibility, extractables, retention method, sterilization compatibility, lot traceability, and applicable certification scope.
SGS and ISO 9001 are listed, but their current documents and relevance to the ordered membrane should be verified before approval.
