Acro Disc Syringe Filters w/ Versapor Membrane, Sterile - 1.2um, 25mm, 50/Pk
Pall SKU: 4190

Pall Acrodisc Acrylic Copolymer Syringe Filters, 1.2 µm, 25 mm, 50/Pk - 4190

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Acrylic copolymer holds consistent absolute retention at the rated pore size while accepting water-based samples without preconditioning and preserves drugs and biologics in the filtrate. Polypropylene construction holds extractable contribution low for sensitive analyses while resisting degradation from routine sample matrices and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Broad compatibility with aqueous solutions, biological fluids, and dilute alcohols
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Low protein and drug binding preserves analytes for maximum recovery
• Highly microporous structure sustains high flow at low differential pressure
• Strong, flexible, non-shedding membrane wet or dry

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.

• Solution Clarification - Provides excellent optical clarity for solutions that typically foul other filters, ensuring consistent visual inspection
• QC Testing - Supports routine pharmaceutical quality control of viscous formulations and syrups requiring consistent particle retention standards
• Particulate Removal - Reliable removal of general particulates from complex matrices and suspensions to protect sensitive downstream instrumentation
• Viscous Filtration - Outperforms standard membranes when filtering heavy oils or concentrated buffers that would typically foul generic filters
• 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
