PolyCap TF 75 PTFE Capsule Filter, 5/Pk SKU: 2703T

PTFE Capsule Filters - 2703T

PTFE capsule filters provide chemically inert filtration for aggressive solvents, corrosive reagents, and gas streams that would compromise other membrane materials. Moreover, 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 filtration process that eliminates cleaning validation, reduces changeover time, and provides batch-to-batch consistency through factory-tested, integrity-verified devices.

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.
• 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.
• Non-sterile configuration accommodates laboratory and industrial applications where the capsule filter serves a clarification or protection function rather than a sterilizing-grade barrier role.
• Internal holdup volume of 22 milliliters minimizes sample loss during capsule filtration, a critical consideration when processing expensive biologics or limited-volume preparations.

Key Capsule Construction Features

• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
• Male or female NPT fittings integrate directly with standard laboratory and industrial pipe fittings, accommodating both rigid and flexible downstream connections.
• Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.
• The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.

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. If your workflow involves organic solvents, aggressive reagents, or process gas streams, the universal chemical resistance of PTFE membrane construction handles the harshest conditions your application presents. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

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.

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.
• Air Filtration - Point-of-use filtration of compressed air and nitrogen gas streams supplying clean manufacturing environments.
• HPLC Preparation - Particle removal from organic and mixed mobile phases prior to high-performance liquid chromatography analysis.
• Solvent Filtration - Chemical-resistant filtration of HPLC mobile phases, aggressive organic solvents, and corrosive reagent solutions.
• Solvent Recovery - Clarification of recycled organic solvents to remove particulates accumulated during previous processing operations.
