LabExact PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10026
A single-use hydrophobic vent filter reaches sterilizing-grade retention on a vent line without the autoclave cycle or in-line housing a reusable gas filtration setup would require. The hydrophobic PTFE membrane provides bacterial retention in gas and vent streams while repelling water and passing gases and solvents freely and suits solvent filtration where other membranes fail. The PP housing is factory-sterilized and individually wrapped for aseptic sample preparation while preserving sample chemistry across the flow path and routes flow to minimize backpressure in service. Downstream equipment and work areas stay protected from airborne bacterial contamination once the vent path runs through the membrane.
Membrane Characteristics
- Insolubility in all known organic solvents avoids swelling and pore distortion
- Chemical resistance spans the full pH 1 to 14 range
- Stable across a wide operating temperature range for demanding methods
- Water contact angle near 120 degrees marks strong hydrophobicity
- Non-fibrous, fully synthetic structure sheds no fibers into filtrate
Housing Characteristics
- Inert polyolefin wall contributes minimal sample adsorption to the filtrate
- Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
- PP housing supplied sterile in individual packaging for immediate use in aseptic filtration without bench preparation
- Withstands ethylene oxide gas sterilization without embrittlement or structural damage
A filter that softens or swells in your solvent fails you mid-run, batch after batch. Solvent-stream filtration handles the solvents and reagents your methods rely on from initial prep through final use.
