Acro Disc Syringe Filters w/ PTFE Membrane - 0.45um, 13mm, Male Slip Luer Outlet, 300/Pk
Pall SKU: 4422

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 13 mm, 300/Pk - 4422

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Hydrophobic PTFE blocks aqueous ingress in vent and gas applications while holding consistent absolute retention at the rated pore size and handles concentrated acids and bases. Polypropylene construction maintains housing integrity through the filtration run while resisting degradation from routine sample matrices and contributes minimal extractables to the filtrate. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods
• Low extractables keep the chromatographic background clean
• Hydrophobic membrane repels water for gas, vent, and solvent filtration

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Tough polypropylene body tolerates repeated handling at the bench
• Resists stress cracking from aqueous salt and buffer solutions
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.

Hydrophobic

• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• Cryogenic Fluids - Delivers consistent performance in extreme temperature environments, filtering cryogenic liquids with exceptional reliability
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• 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
