Pall SKU: 4472

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 4 mm, 750/Pk - 4472

Pall applies its proprietary membrane manufacturing capabilities, integrating specialized media into the Acrodisc housing geometry. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. PTFE stays chemically inert against aggressive solvents, strong acids, and alkalis in service and suits gas, vent, and solvent-stream filtration. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while contributing minimal extractables to the filtrate and maintains a low-dead-volume internal flow path. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body holds its shape under manual filtration pressure

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis.
