Polypropylene Capsule Filter, 0.45um, 1/4" NPTM, Nonsterile, 1/Pk
GVS SKU: 1213596

Featuring a 0.45um hydrophobic polypropylene membrane housed in a chemically resistant polypropylene capsule, this disposable filtration unit removes particles or bacteria from aqueous solutions, solvent solutions, and gas streams. It arrives ready to use, eliminating the need to disassemble, clean, and reassemble filter housings, and connects inline through 1/4" NPTM fittings. The unit is supplied nonsterile, packaged one per pack.

Key Polypropylene Membrane Characteristics

• Naturally hydrophobic polypropylene media suited to aqueous, solvent, and gas-stream filtration
• Serial layer filter design that increases throughput and extends service life
• Contains no glue or surfactants, supporting clean sample handling
• Membrane media preflushed with purified water to reduce extractables
• Broad chemical compatibility for solvent-based and process applications

Key Construction Characteristics

• Polypropylene housing that is food compliant (FDA/EU) and chemically resistant to organics
• 1/4" NPTM inlet and outlet connections for inline installation
• Two upstream vents to facilitate venting in any position
• Nonsterile, packaged 1 per pack
• Passes Class VI toxicology testing and is integrity tested prior to shipment

This capsule delivers reliable, ready-to-use filtration while maintaining sample integrity through its glue-free, surfactant-free construction. The serial layer media sustains throughput on heavily loaded samples, and the integrity-tested polypropylene housing provides dependable performance across aqueous, solvent, and gas-phase applications.
