Acro Disc Syringe Filters w/ Nylon Membrane - 0.2um, 25mm, 200/Pk
Pall SKU: 4436

Pall Acrodisc Nylon Syringe Filters, 0.2 µm, 25 mm, 200/Pk - 4436

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The nylon membrane holds dimensional stability under rated backpressure and resists alkaline buffer systems. The PP housing prevents sample bypass under rated operating pressure and routes flow to minimize backpressure in service. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• High tensile strength for stability under elevated differential pressures
• Alkaline-resistant across a broad range of aqueous buffers
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Absolute pore size rating provides consistent results across filtration protocols
• Non-sterile for routine clarification and sample prep

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Low extractable contribution protects sensitive downstream analyses
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.
