PolyCap TF 36 PTFE Capsule Filter, 5/Pk SKU: 2601T

PTFE Capsule Filters - 2601T

PTFE capsule filters bring the chemical inertness required for solvent processing and gas filtration into a disposable, integrity-testable format suited to regulated environments. At its core, pleated PTFE membrane construction provides extended surface area for solvent and gas filtration, maintaining flow performance across high-volume batches where chemical resistance is the primary selection criterion. The result is a streamlined filtration step that integrates directly into fluid transfer systems, reducing hold times and minimizing the manual handling that compromises sterility assurance.

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.
• 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 hydrophobic PTFE membrane serves both liquid solvent filtration and sterile gas venting applications, with alcohol pre-wetting required only for aqueous solution processing.
• PTFE membrane capsules resist degradation by virtually all organic solvents, strong acids, bases, and oxidizing agents, providing universal chemical compatibility for aggressive filtration applications.
• Maximum operating pressure of 60 psi provides the differential pressure capacity needed for sustained filtration of viscous solutions and high-flow process streams.

Key Capsule Construction Features

• 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 supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.
• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.

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. In response, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Sterilization Guidance
