PTFE Capsule Filters - SF15006

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. From a technical standpoint, the chemically inert PTFE membrane within the capsule housing resists degradation by virtually all organic solvents, strong acids, and alkaline solutions, enabling filtration of the most aggressive process fluids. Taken together, 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

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.
The 80 degree Celsius temperature limit ensures reliable capsule performance for ambient and moderately heated filtration applications.
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.
The 75.4 psi maximum pressure rating accommodates the differential pressures generated during filtration of particle-laden solutions as the membrane progressively loads.
PTFE membrane chemistry withstands autoclave temperatures, supporting sterilization protocols where both the membrane and housing construction are rated for steam exposure.

Key Capsule Construction Features

Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
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 capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.

When your filtration protocol calls for a validated, integrity-testable barrier that arrives ready to connect and begins filtering immediately, the capsule format delivers that capability without the overhead of traditional filter assemblies. In practice, 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Sterilization Guidance

Standard autoclave cycles at 121 degrees Celsius are compatible with the polypropylene housing and membrane assembly, allowing preparation for sterile applications at the point of use.
