LabExact PTFE Syringe Filters, 0.22 µm, 17 mm, 100/Pk - LE-IWT-ES10320

A syringe filter with a hydrophobic vent-rated membrane keeps gas and vent lines free of microbial ingress. The PTFE membrane withstands aggressive organics that degrade other media while achieving sterile-grade retention in gas and vent service and filters aggressive organic solvents without breakdown. The PP housing sustains efficient flow on viscous samples while holding its seal true run after run and delivers a chemically clean filtrate to the downstream step. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Membrane Characteristics

• Surface energy near 18.5 dynes per centimeter repels oils and nonpolar liquids
• Chemical resistance spans the full pH 1 to 14 range
• Non-wetting pore surface blocks liquid water while passing water vapor freely
• Minimal moisture absorption pairs with a low tare mass
• Ionic and metallic extractable levels stay very low

Housing Characteristics

• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body maintains its geometry through routine filtration pressure

An aggressive solvent can leach or break down a vulnerable filter and carry debris into your prep. Solvent-stream filtration handles the solvents and reagents your methods rely on from initial prep through final use.
