PTFE Capsule Filters - 6710-3602

PTFE capsule filters bring the chemical inertness required for solvent processing and gas filtration into a disposable, integrity-testable format suited to regulated environments. Underpinning this performance, PTFE membrane stability at elevated temperatures supports both liquid filtration and sterile gas venting applications, with capsule construction rated for the operating pressures encountered in process-scale systems. Consequently, the outcome is a validated filtration barrier that arrives ready for process integration, supporting the single-use manufacturing strategies adopted by modern pharmaceutical and biotechnology facilities.

Key PTFE Membrane Characteristics

• Chemical inertness of the PTFE membrane ensures that filtered solvents and gases pass through without extractable contamination, meeting the purity requirements of HPLC mobile phase preparation and analytical applications.
• The non-sterile capsule format offers a cost-effective option for applications where particle removal rather than sterility assurance is the primary filtration objective.
• PTFE capsule filters maintain mechanical integrity and retention performance at temperatures exceeding those tolerated by PES, PVDF, or nylon membranes, supporting high-temperature process filtration.
• PTFE membrane chemistry withstands autoclave temperatures, supporting sterilization protocols where both the membrane and housing construction are rated for steam exposure.
• The pleated PTFE membrane configuration within the capsule housing provides sufficient surface area for production-scale solvent filtration without the pressure drops associated with flat disc PTFE devices.

Key Capsule Construction Features

• Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
• Stepped hose barb design accommodates multiple tubing sizes on a single fitting, simplifying inventory management and enabling connection flexibility across different process configurations.
• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.

Whether your process requires sterilizing-grade retention for a 500-milliliter bench trial or clarification capacity for a 100-liter production batch, the right capsule filter configuration eliminates the compromises between throughput, retention, and operational simplicity. Here, for laboratories and production facilities filtering HPLC mobile phases, aggressive chemicals, or sterile gases, PTFE capsule filters provide the chemical inertness your purity standards demand. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Sterilization Guidance

Supplied non-sterile, the polypropylene housing supports autoclave sterilization at 121 degrees Celsius for 20 minutes when aseptic filtration is required by the application protocol.

Hydrophobic

• Chemical Processing - Filtration of strong acids, bases, and aggressive organic chemicals that degrade PES, PVDF, and nylon membranes.
• Tank Venting - Hydrophobic membrane barrier prevents microbial ingress while allowing pressure equalization in process tank headspaces.
• Solvent Filtration - Chemical-resistant filtration of HPLC mobile phases, aggressive organic solvents, and corrosive reagent solutions.
• HPLC Preparation - Particle removal from organic and mixed mobile phases prior to high-performance liquid chromatography analysis.
• Solvent Recovery - Clarification of recycled organic solvents to remove particulates accumulated during previous processing operations.
• Vent Protection - Membrane barrier filtration for fermentation vessel exhaust and bioreactor off-gas systems in bioprocessing facilities.
