PolyCap TF 75 PTFE Capsule Filter, 5/Pk SKU: 2702T

PTFE Capsule Filters - 2702T

The broad chemical compatibility and thermal resistance of PTFE capsule filters make them a reliable choice for filtration tasks spanning organic chemistry, pharmaceutical manufacturing, and process gas handling. The chemically inert PTFE membrane within the capsule housing resists degradation by virtually all organic solvents, strong acids, and alkaline solutions, enabling filtration of the most aggressive process fluids. On this basis, the outcome is higher operational throughput with lower contamination risk, as disposable capsule devices remove the reprocessing steps that introduce variability into reusable filter systems.

Key PTFE Membrane Characteristics

• The hydrophobic PTFE membrane serves both liquid solvent filtration and sterile gas venting applications, with alcohol pre-wetting required only for aqueous solution processing.
• Rated for operating pressures up to 60 psi, the capsule housing withstands the system pressures encountered in peristaltic pump, pressure vessel, and gravity-feed filtration configurations.
• 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.
• 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 capsules resist degradation by virtually all organic solvents, strong acids, bases, and oxidizing agents, providing universal chemical compatibility for aggressive filtration applications.

Key Capsule Construction Features

• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
• The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.
• Polypropylene capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.

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. When your application requires a membrane that withstands both chemical attack and elevated temperatures, PTFE construction delivers the durability your process conditions require without sacrificing retention performance. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Sterilization Guidance

Non-sterile delivery accommodates applications where sterility is not required, while the all-polypropylene construction provides the option for autoclave sterilization when aseptic processing is specified.
