LabExact PTFE Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10024

A syringe filter with a hydrophobic vent-rated membrane keeps gas and vent lines free of microbial ingress. The hydrophobic PTFE membrane suits gas, vent, and solvent-stream filtration while achieving sterile-grade retention in gas and vent service and filters aggressive organic solvents without breakdown. The polypropylene housing holds its seal true run after run and stands firm against aqueous acids, bases, and alcohols during regular handling. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Membrane Characteristics

• Non-wetting pore surface blocks liquid water while passing water vapor freely
• Water contact angle near 120 degrees marks strong hydrophobicity
• Surface energy near 18.5 dynes per centimeter repels oils and nonpolar liquids
• UL 94 V-0 rating confirms the highest self-extinguishing classification
• Biological inertness resists enzymatic attack from proteases and lipases

Housing Characteristics

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Medical-grade polypropylene with broad chemical compatibility
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run.

Hydrophobic

• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, delivering pure filtrate quality consistently.
• Pump Protection - Acts as a hydrophobic barrier that protects vacuum pumps from corrosive moisture and particulate damage.
• Agrochemical Formulation QC - Clarifies technical pesticide concentrates in organic solvent ahead of HPLC potency and impurity analysis.
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in demanding atmospheric monitoring conditions.
• Mobile Phase Prep - Extends column life by consistently removing particulates from organic HPLC mobile phases before every injection.
• Polymer GPC Prep - Clarifies polymer solutions in THF ahead of gel permeation chromatography, protecting columns from particulates.
