Pall Acrodisc Acrylic Copolymer Syringe Filters, 5 µm, 25 mm, 50/Pk - 4199

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Acrylic copolymer keeps protein and drug binding low for faithful recovery while passing viscous, difficult-to-filter solutions with ease and suits aqueous solutions and biological fluids. Polypropylene construction holds extractable contribution low for sensitive analyses 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 protein and drug binding preserves analytes for maximum recovery
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Broad compatibility with aqueous solutions, biological fluids, and dilute alcohols
• Strong, flexible, non-shedding membrane wet or dry
• Highly microporous structure sustains high flow at low differential pressure

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench
• 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.

• Particulate Removal - Reliable removal of general particulates from complex matrices and suspensions to protect sensitive downstream instrumentation
• Serum Analysis - Clarifies serum and plasma samples efficiently while maintaining fast flow rates to support high-throughput clinical workflows
• Prefiltration - Handles difficult-to-filter viscous solutions without premature blocking or backpressure buildup to ensure process efficiency
• QC Testing - Supports routine pharmaceutical quality control of viscous formulations and syrups requiring consistent particle retention standards
• Viscous Filtration - Outperforms standard membranes when filtering heavy oils or concentrated buffers that would typically foul generic filters
• Solution Clarification - Provides excellent optical clarity for solutions that typically foul other filters, ensuring consistent visual inspection
