Pall SKU: AP-4790

Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 200/Pk - AP-4790

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. 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 resisting attack from the harshest process chemistries and filters aggressive organic solvents without breakdown. The polypropylene housing holds a reliable seal against the membrane edge while keeping the fluid path low in extractable contamination and resists degradation from routine sample matrices. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

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
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Resists stress cracking from aqueous salt and buffer solutions
• Stable across the full aqueous pH range in routine sample work
• Plasticizer-free polyolefin construction keeps the fluid path clean

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 so your downstream method starts with a clean sample.

• Gas Filtration - Ensures sterility in air and gas lines for fermentation tanks, preventing the introduction of airborne contaminants
• 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
• 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
