PTFE Capsule Filter, 0.45um, Size 10in, 1/4in NPTM, Nonsterile, 1/Pk
GVS SKU: 1212992

Featuring a naturally hydrophobic polytetrafluoroethylene (PTFE) membrane rated at 0.45um, this disposable Calyx capsule filter is built for the removal of particles or bacteria from solvent solutions and gas streams. The size 10in unit provides a generous 0.55 m² of filtration area and terminates in a 1/4in NPTM connection, arriving ready to use so there is no need to disassemble, clean, and reassemble filter housings. A serial layer filter design increases throughput and extends service life, while two upstream vents facilitate venting in any orientation.

Key PTFE Membrane Characteristics

• Naturally hydrophobic PTFE media suited to chemical, vent, acid, base, and oxidant filtration as well as process air and gas filtration.
• Broad chemical compatibility for aggressive solvents and bulk or electronics-grade chemicals.
• 0.45um pore size for particulate and bacterial removal from solvent solutions and gas streams.
• Serial layer filter construction increases throughput and extends filter life.
• Contains no glue or surfactants, and membrane media are pre-flushed with purified water to reduce extractables.

Key Construction Characteristics

• Disposable capsule format in the size 10in configuration with 0.55 m² of effective filtration area.
• 1/4in NPTM (male NPT) inlet/outlet connection.
• Two upstream vents included to facilitate venting in any position.
• Nonsterile, supplied 1 per pack in low particulate packaging.
• Passes Class VI toxicology testing and is integrity tested prior to shipment.

This ready-to-use capsule delivers consistent, reliable filtration performance across demanding chemical and gas streams. The glue-free, surfactant-free serial layer build maintains sample integrity while protecting downstream processes from particulate breakthrough.

Hydrophobic

• Chemical Filtration The hydrophobic PTFE membrane handles aggressive acids, bases, oxidants, and bulk or electronics-grade chemicals with broad compatibility.
• Process Air and Gas Filtration Hydrophobic media makes the capsule well suited to inline filtration and particulate removal from air and gas streams.
• Sterile Venting The PTFE media supports venting of tanks and vessels where a hydrophobic barrier is required.
• Solvent Clarification The 0.45um membrane removes particulates from solvent solutions ahead of downstream analysis or processing.
• High-Throughput Filtration The size 10in capsule with 0.55 m2 of area and serial layer design supports large-volume runs with extended life.
• Downstream Membrane Protection Capturing particulates upstream protects finer filters and instrumentation from premature fouling.
