Tisch Scientific PVDF Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SPEC18212

Tisch Scientific customer service specialists focus on laboratory products and can help source the right solution for specific applications. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. The hydrophobic PVDF membrane blocks aqueous ingress in venting applications while achieving sterile-grade retention at sub-micron pore sizes and resists HPLC mobile phases, alcohols, and mild hydrocarbons. The polypropylene housing routes flow to minimize backpressure in service and holds a reliable seal against the membrane edge. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Sterilizing-grade retention at sub-micron pore sizes
• Mechanically durable membrane holds integrity under filtration pressure
• Hydrophobic membrane repels water for dependable gas and vent filtration
• Thin membrane structure sustains high flow for fast sample throughput

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection.

• HPLC Mobile Phase Preparation - Remove particulates from mobile phases before they reach columns to extend column life and ensure baseline stability
• LC-MS Sample Processing - Filter biological samples before mass spectrometry to protect ionization sources while preserving analyte integrity
• Organic Solvent Filtration - Process aggressive solvents, including acetonitrile and chloroform, where chemical compatibility prevents degradation
• Chemical Reagent Sterilization - Remove bacteria from aggressive organic solvents and chemical reagents to ensure sterility in critical applications
• Final Product Sterilization - Achieve sterile filtration of heat-sensitive formulations where terminal sterilization would compromise stability
• Environmental Analysis - Prepare water and soil extracts for chromatography by removing suspended solids that interfere with sensitive detection
