Acro Disc PSF Syringe Filters w/ PTFE Membrane - GxF/0.45um, 25mm, 1000/Pk
Pall SKU: AP-4302

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 25 mm, 1000/Pk - AP-4302

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. Hydrophobic PTFE blocks aqueous ingress in vent and gas applications and delivers absolute particle cutoff at the rated pore size. The PP housing keeps the fluid path low in extractable contamination and routes flow to minimize backpressure in service. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• 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
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Optimized internal geometry minimizes backpressure in service
• Resists stress cracking from aqueous salt and buffer solutions
• Resists aqueous acids, bases, and alcohols in routine sample prep

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 from reaction mixtures and crude extracts through final analysis.
