Versapor Acrylic Copolymer 450 Membrane Disc Filters, 0.45um - 47mm, 100/Pk SKU: 66408

Versapor Membrane Filters - 66408

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66408 provides the filtration consistency that method validation demands. Naturally wettable surface eliminates the need for surfactant pre-treatment, reducing the risk of additive interference in sensitive biological and diagnostic assays. Lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• High tensile strength and flexibility allow Versapor membranes to withstand the mechanical stress of roll-to-roll processing and automated handling systems.
• Versapor acrylic copolymer membranes provide a unique combination of hydrophilicity and mechanical flexibility not available from standard PES or nylon membranes.
• Maximum operating temperature of 88°C accommodates warm sample filtration and elevated-temperature processes that exceed the limits of standard devices.
• Naturally hydrophilic surface wets instantly on contact with aqueous solutions, supporting rapid vacuum filtration without pre-conditioning steps.
• Chemical resistance to common processing agents enables integration of Versapor membranes into devices requiring post-assembly gamma or EtO treatment.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. To support this, the chemical compatibility range documented for this device allows you to verify suitability for your specific sample matrix before processing, avoiding the mid-filtration failures that waste both sample and time. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Automated Tape Sampling - Provides the tensile strength needed for roll-to-roll air monitoring systems that index fresh filter tape automatically.
• Proteomic Sample Prep - Clarifies viscous lysates prior to mass spectrometry, removing large debris without stripping hydrophobic peptides.
• Diagnostic Strip Wicking - Acts as a reliable sample pad in lateral flow tests, controlling the rate of fluid release onto the reaction membrane.
• Blood Serum separation - Separates serum from whole blood in vertical flow devices, trapping red cells while allowing clean serum to pass.
• Fluid Venting Barriers - Integrated into IV spikes to allow air to enter the bottle while preventing the liquid medication from leaking out.
• Airborne Metals Analysis - Captures industrial dust for acid digestion and analysis, ensuring accurate monitoring of workplace exposure limits.
