PolyCap TF 150 PTFE Capsule Filter, 5/Pk SKU: 2802T

PTFE Capsule Filters - 2802T

When filtration applications involve strong acids, concentrated organics, or high-temperature gases, PTFE capsule filters offer universal chemical resistance in a ready-to-use format. Engineered for demanding applications, 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. As designed, 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

• Single-layer membrane construction provides direct, absolute retention at the rated pore size without the additional flow resistance introduced by upstream prefilter layers.
• 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.
• Internal holdup volume of 43 milliliters minimizes sample loss during capsule filtration, a critical consideration when processing expensive biologics or limited-volume preparations.
• 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.

Key Capsule Construction Features

• Polypropylene capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
• 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.
• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.

From method development through scale-up to production, your capsule filter choice defines the balance between membrane performance, process integration, and the regulatory documentation trail that supports each filtration event. 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. 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.
