Pall SKU: 4555

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 13 mm, 1000/Pk - 4555

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Chemically inert PTFE resists attack from the harshest process chemistries while clarifying solvent streams at the rated pore size and blocks aqueous ingress in vent applications. The PP housing sustains efficient flow on viscous samples and keeps the fluid path low in extractable contamination. 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
• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Tough polypropylene body tolerates repeated handling at the bench
• Stable across the full aqueous pH range in routine sample work
• Resists stress cracking from aqueous salt and buffer solutions

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids, ensuring compatibility with the harshest synthetic reaction mixtures
• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• Cryogenic Fluids - Delivers consistent performance in extreme temperature environments, filtering cryogenic liquids with exceptional reliability
• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
