Pall Acrodisc PTFE Syringe Filters, 1 µm, 25 mm, 1000/Pk - 4503

Pall's engineering and quality infrastructure extends from its process-scale filtration systems to its laboratory devices. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Hydrophobic PTFE blocks aqueous ingress in vent and gas applications while filtering aggressive organic solvents without breakdown and withstands aggressive organics that degrade other media. The PP housing stays inert across common laboratory solvents and buffers in routine use and maintains housing integrity through the filtration run. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• 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

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Tough polypropylene body tolerates repeated handling at the bench

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis.

• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
• 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
