Versapor Acrylic Copolymer 450 Membrane Disc Filters, 0.45um - 142mm, 25/Pk SKU: 66410

Versapor Membrane Filters - 66410

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66410 provides the filtration consistency that method validation demands. Complementing this, naturally wettable surface eliminates the need for surfactant pre-treatment, reducing the risk of additive interference in sensitive biological and diagnostic assays. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Versapor acrylic copolymer membranes provide a unique combination of hydrophilicity and mechanical flexibility not available from standard PES or nylon membranes.
• Broad compatibility with diagnostic reagents and biological fluids makes Versapor a reliable membrane for lateral flow device and blood separation applications.
• High tensile strength and flexibility allow Versapor membranes to withstand the mechanical stress of roll-to-roll processing and automated handling systems.
• Naturally hydrophilic surface wets instantly on contact with aqueous solutions, supporting rapid vacuum filtration without pre-conditioning steps.
• Controlled porosity delivers consistent flow rates and predictable retention characteristics across production lots for device manufacturing reproducibility.

Reproducible particle counting starts with a membrane surface that captures particles uniformly. The pore consistency documented above ensures your counts reflect the sample, not filter variation. To address this, complete specification documentation for this device supports the traceability requirements of your quality system, providing the recorded evidence of consumable performance that auditors and method reviewers expect to see. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Cleanroom Monitoring - Used in active air samplers to collect viable particles in cleanrooms for subsequent culture and identification.
• Automated Tape Sampling - Provides the tensile strength needed for roll-to-roll air monitoring systems that index fresh filter tape automatically.
• Microplastic Counting - Provides a high-contrast background for identifying colored microplastics in environmental water or sand extracts.
• Airborne Metals Analysis - Captures industrial dust for acid digestion and analysis, ensuring accurate monitoring of workplace exposure limits.
• Diagnostic Strip Wicking - Acts as a reliable sample pad in lateral flow tests, controlling the rate of fluid release onto the reaction membrane.
• Proteomic Sample Prep - Clarifies viscous lysates prior to mass spectrometry, removing large debris without stripping hydrophobic peptides.
