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

PTFE Capsule Filters - 2702M

Laboratories and pilot plants that filter organic solvents or vent process gases turn to PTFE capsule filters for their unmatched chemical stability and thermal tolerance. On the performance side, 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. In effect, the result is a filtration workflow that scales efficiently from method development through production, delivering consistent retention performance across the full range of capsule effective filtration areas.

Key PTFE Membrane Characteristics

• 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.
• The hydrophobic PTFE membrane serves both liquid solvent filtration and sterile gas venting applications, with alcohol pre-wetting required only for aqueous solution processing.
• 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.
• 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.

Key Capsule Construction Features

• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.
• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.
• Male or female NPT fittings integrate directly with standard laboratory and industrial pipe fittings, accommodating both rigid and flexible downstream connections.

Your laboratory's filtration throughput depends not only on membrane retention characteristics but on the practical factors of device connection, priming, and changeover that capsule filters are specifically engineered to optimize. For this purpose, 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.
