Polypropylene Filter Holder, 25mm, Hydrophilic, Autoclavable, Reusable, Nonsterile, 10/Pk
GVS SKU: 1214526

Featuring a durable polypropylene housing, this reusable 25mm in-line filter holder secures 25mm disc membranes for ultracleaning and sterilizing small volumes of liquid dispensed from a syringe, typically filtering up to 50 mL of sample. The polypropylene construction delivers a broad chemical compatibility range and withstands temperatures up to 121C, allowing the unit to be autoclaved and reused. An inlet cap that locks into the base prevents twisting damage to the membrane as the cap is tightened, while projection lugs on the base and cap allow quick, efficient assembly and sealing by hand.

Key Construction Characteristics

• Housing and support screen molded from polypropylene (PP) for durability and excellent resistance to a wide range of solvents, acids, and bases
• Hydrophilic flow path suited to general aqueous and solvent filtration
• Dual support screens prevent membrane rupture under back pressure and allow bi-directional sample flow
• Inlet cap locks into the base and exterior locking ring seals by simple hand tightening without tearing the membrane
• Withstands temperatures up to 121C and may be autoclaved for reuse

Sealing and Reuse

• O-ring sealing helps prevent leaks across membrane types
• Two-piece design allows fast membrane replacement and cleaning between uses
• Supplied nonsterile, 10 holders per pack

The polypropylene body maintains its integrity through repeated autoclave cycles, providing dependable, leak-resistant filtration run after run. By securing the membrane against tearing and twisting during assembly, the holder protects sample integrity and supports accurate, reproducible results.

Hydrophilic

• Small-Volume Liquid Filtration Filters and clarifies sample volumes up to 50 mL dispensed from a syringe through a user-supplied 25mm membrane.
• Aseptic Sampling Enables collection of liquids or gases at point-of-use when samples must be processed on-site.
• Solvent and Aqueous Filtration Handles general aqueous and solvent streams thanks to the broad chemical compatibility of the polypropylene body.
• Bi-Directional In-Line Processing Dual support screens allow flow in either direction for in-line filtration setups.
• Membrane Reuse Workflows Autoclavable two-piece design supports repeated use with replaceable 25mm disc membranes, reducing consumable waste.
• Air and Gas Analysis Supports air analysis and aseptic gas sampling when paired with an appropriate membrane.
