Acro Disc PSF Syringe Filters w/ PTFE Membrane - 0.2um, 25mm, 1000/Pk
Pall SKU: AP-4521

Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - AP-4521

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PTFE filters aggressive organic solvents without swelling or breakdown and delivers sterilizing-grade gas and vent filtration. Polypropylene construction resists chemical degradation from routine sample matrices while sustaining efficient flow on viscous samples and maintains housing integrity through the filtration run. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Low extractables keep the chromatographic background clean
• Absolute pore size rating gives consistent results across protocols
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Thermal-bonded construction keeps adhesives out of the fluid path
• Plasticizer-free polyolefin construction keeps the fluid path clean

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 so your filter holds its integrity through the run.

• 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
• Gas Filtration - Ensures sterility in air and gas lines for fermentation tanks, preventing the introduction of airborne contaminants
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• 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
