Polypropylene Filter

Polypropylene membranes exhibit broad chemical compatibility and utility in a wide range of applications. Our portfolio includes both a hydrophobic and hydrophilic version which allows the membranes to be used with both aqueous and organic samples.

Hydrophobic

The hydrophobic polypropylene membrane is a pure polymer which results in high chemical stability and minimizes the concern over extractables. Additional features of the membrane include resistance to high temperatures and the ability to be autoclaved. Available in a 0.1 µm pore size, the hydrophobic polypropylene membrane is ideal for the filtration of aggressive solvents. Compared to PTFE membranes, this material is a more economical option for use in venting applications, which require the exchange of air and gas but cannot allow liquids to pass through the membrane.

Hydrophilic

The hydrophilic nature and broad chemical compatibility of the membrane allows for the efficient filtration of both aqueous and organic solutions resulting in maximum versatility. When used in analytical sample preparation applications, the membrane will not yield extractables or add artifacts to the sample for analysis. For biological samples, the hydrophilic polypropylene membrane gives high recoveries of critical proteinaceous samples and confers low, non-specific binding. In screening applications where membrane background interference is a concern, our hydrophilic polypropylene membrane yields extremely low levels of autofluorescence.

Chemically Resistant, High-Performance Polypropylene Filters for Demanding Applications

Ensure reliable, contamination-free filtration in aggressive chemical and industrial environments with our Polypropylene (PP) Filter —robust, hydrophobic or hydrophilic membrane filters engineered for solvent filtration, venting, air purification, and harsh aqueous solutions. Made from pure, biologically inert polypropylene, these filters offer exceptional chemical compatibility, high thermal stability, and low extractables, making them ideal for pharmaceutical, chemical, and environmental laboratories.

Built for Tough Conditions

Our Polypropylene Filters resist a wide range of organic solvents, acids, and bases (including strong alkalis), outperforming cellulose-based membranes in corrosive applications. Available in pore sizes from 0.1 µm to 5.0 µm and in multiple formats—including syringe filters, disc membranes, and capsule filters—they support sterile filtration, gas venting, HPLC sample prep, and particle removal in both liquid and air streams.

Excellent Chemical Resistance – Stable in most organic solvents, acids, and bases (except strong oxidizing agents).
Hydrophobic & Hydrophilic Options – Choose based on application: hydrophobic for gas/air filtration, hydrophilic for aqueous solutions.
High Thermal Tolerance – Autoclavable at 121°C and usable up to 130°C for short durations.
Low Protein Binding & Extractables – Preserves sample integrity in sensitive analytical and biological workflows.
High Flow Rates & Dirt Holding Capacity – Efficient filtration with extended service life.
ISO-Certified Manufacturing – Produced in controlled environments for consistent quality and low endotoxin levels.

Trusted Across Industries

From filtering aggressive reagents in synthetic chemistry to venting bioreactors and purifying process gases, Polypropylene Filters are the go-to choice when chemical compatibility and durability matter. Their rugged structure maintains integrity under pressure or vacuum, while their purity supports compliance with USP, EP, and GMP standards.

Whether you’re handling solvents, acids, or high-purity water, our PP filters deliver dependable performance—run after run.

Choose polypropylene for filtration that stands up to the toughest challenges.
