Acro Disc PSF Syringe Filters w/ PTFE Membrane - GxF/0.45um, 25mm, 200/Pk
Pall SKU: AP-4303

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 25 mm, 200/Pk - AP-4303

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The PTFE matrix handles concentrated acids and bases across demanding methods and repels water while passing gases and solvents freely. The polypropylene housing contributes minimal extractables to the filtrate and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Stable across a wide operating temperature range for demanding methods
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Plasticizer-free polyolefin construction keeps the fluid path clean

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.

Hydrophobic

• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids, ensuring compatibility with the harshest synthetic reaction mixtures
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Cryogenic Fluids - Delivers consistent performance in extreme temperature environments, filtering cryogenic liquids with exceptional reliability
• Gas Filtration - Ensures sterility in air and gas lines for fermentation tanks, preventing the introduction of airborne contaminants
• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
