PolyCap TF 150 PTFE Capsule Filter, 5/Pk SKU: 2804T

PTFE Capsule Filters - 2804T

PTFE capsule filters bring the chemical inertness required for solvent processing and gas filtration into a disposable, integrity-testable format suited to regulated environments. 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. With this in mind, 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

• Capsule holdup volume of 43 milliliters represents the fluid retained within the device after filtration, an important factor when calculating yield for high-value pharmaceutical products.
• PTFE membrane chemistry withstands autoclave temperatures, supporting sterilization protocols where both the membrane and housing construction are rated for steam exposure.
• The hydrophobic PTFE membrane serves both liquid solvent filtration and sterile gas venting applications, with alcohol pre-wetting required only for aqueous solution processing.
• The 121 degree Celsius temperature limit ensures reliable capsule performance for ambient and moderately heated filtration applications.
• Single-membrane construction simplifies integrity test interpretation, as the bubble point and diffusion flow values correspond directly to the rated retention membrane without prefilter interference.

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.
• NPT threaded connections provide secure, wrench-tightened installation for process applications requiring higher connection pressures than push-fit alternatives.
• 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.

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. To support this, 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.
