PolyCap TF 75 PTFE Capsule Filter, 5/Pk SKU: 2700T

PTFE Capsule Filters - 2700T

The broad chemical compatibility and thermal resistance of PTFE capsule filters make them a reliable choice for filtration tasks spanning organic chemistry, pharmaceutical manufacturing, and process gas handling. 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. Together, 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

• 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.
• Non-sterile capsule delivery is appropriate for clarification, prefiltration, and general laboratory applications where the filtrate does not require sterility assurance.
• Without an integrated prefilter, the full effective filtration area is dedicated to final retention, maximizing the available membrane surface for applications with clean or pre-filtered feed solutions.
• The hydrophobic PTFE membrane serves both liquid solvent filtration and sterile gas venting applications, with alcohol pre-wetting required only for aqueous solution processing.

Key Capsule Construction Features

• 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.
• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.

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. Under these conditions, 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. 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.
