Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.45um, 13mm, 75/Pk
Pall SKU: 4604

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 75/Pk - 4604

Pall applies its proprietary membrane manufacturing capabilities, integrating specialized media into the Acrodisc housing geometry. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Low-binding PES preserves dilute proteins and analytes in the filtrate while handling strong bases across a broad aqueous range and draws aqueous samples through without pre-wetting. Polypropylene construction resists chemical degradation from routine sample matrices and keeps the fluid path low in extractable contamination. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Stable across the full pH 1 to 14 operating range
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Absolute pore size rating gives consistent results across protocols
• High flow rate with low extractable background for clean preparations
• Low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists stress cracking from aqueous salt and buffer solutions

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.
