Acro Disc PSF Syringe Filters w/ PTFE Membrane - 0.45um, 25mm, 1000/Pk
Pall SKU: AP-4501

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 25 mm, 1000/Pk - AP-4501

Pall's engineering and quality infrastructure extends from its process-scale filtration systems to its laboratory devices. Across analytical workflows, the syringe filter is where particulates leave the sample stream. PTFE delivers absolute particle cutoff at the rated pore size and stays chemically inert against solvents, acids, and alkalis. The polypropylene housing routes flow to minimize backpressure in service and resists aqueous acids, bases, and alcohols. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Stable across the full aqueous pH range in routine sample work

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples so your downstream method starts with a clean sample.
