LabExact Tri-Layer PVDF Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10406

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. Hydrophobic PVDF repels water for dependable gas and vent filtration while providing sterilizing-grade retention at sub-micron pore sizes and holds up to alcohols and mild hydrocarbon solvents. Polypropylene construction maintains a low-dead-volume internal flow path and presses snugly against the membrane during the pass. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Membrane Characteristics

• Fluorinated polymer chemistry resists ozone, UV, and ionizing radiation
• Fluoropolymer chemistry resists microbial and fungal degradation
• Vapor-phase hydrogen peroxide decontamination cycles leave the membrane intact
• Organic solvent resistance beats PES or nylon at comparable pore size
• Cast membrane structure releases no fibers, unlike depth-media prefilters

Housing Characteristics

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Translucent housing wall allows visual confirmation of sample flow during filtration

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 across the organic solvents and harsh reagents your methods use.

• QuEChERS Extract Prep - Removes co-extracted waxes and pigments from QuEChERS extracts, protecting GC-MS and LC-MS systems during pesticide testing.
• Dissolution Testing - Removes undissolved particles from timed USP 711 dissolution aliquots, preventing skewed potency and release results.
• Sterile Tank Venting - Blocks aqueous ingress on storage tanks and carboys, letting sterile air and gas pass through the vent line.
• Compressed Gas Filtration - Passes nitrogen and other inert gases freely while holding back moisture, protecting instruments and gas lines.
• Bioreactor Vent Protection - Repels water while venting bioreactors and fermenters, keeping process air and gases moving freely through the line.
• Vial and Tubing Venting - Blocks liquid while venting sealed vials and tubing lines, keeping pressure equalized during fluid transfer steps.
