Versapor Acrylic Copolymer 3000 Membrane Disc Filters, 3 um - 25mm, 100/Pk SKU: 66386

Versapor Membrane Filters - 66386

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66386 provides the filtration consistency that method validation demands. Acrylic copolymer membrane construction delivers a naturally hydrophilic, mechanically flexible filtration surface with broad compatibility across aqueous and mild organic solutions. Consequently, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• High tensile strength and flexibility allow Versapor membranes to withstand the mechanical stress of roll-to-roll processing and automated handling systems.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Maximum operating temperature of 88°C accommodates warm sample filtration and elevated-temperature processes that exceed the limits of standard devices.
• Controlled porosity delivers consistent flow rates and predictable retention characteristics across production lots for device manufacturing reproducibility.
• Chemical resistance to common processing agents enables integration of Versapor membranes into devices requiring post-assembly gamma or EtO treatment.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. Here, consistent manufacturing means the filtration performance you observe during initial evaluation repeats on every subsequent unit, supporting the reproducibility your quality system requires. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• 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.
• Blood Serum separation - Separates serum from whole blood in vertical flow devices, trapping red cells while allowing clean serum to pass.
• Diagnostic Strip Wicking - Acts as a reliable sample pad in lateral flow tests, controlling the rate of fluid release onto the reaction membrane.
• Fluid Venting Barriers - Integrated into IV spikes to allow air to enter the bottle while preventing the liquid medication from leaking out.
• Microplastic Counting - Provides a high-contrast background for identifying colored microplastics in environmental water or sand extracts.
