Versapor Acrylic Copolymer 800 Membrane Disc Filters, 0.8um - 47mm, 100/Pk SKU: 66401

Versapor Membrane Filters - 66401

Precision-manufactured Hydrophilic membrane with a verified 0.8 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Building on this foundation, naturally wettable surface eliminates the need for surfactant pre-treatment, reducing the risk of additive interference in sensitive biological and diagnostic assays. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Controlled porosity delivers consistent flow rates and predictable retention characteristics across production lots for device manufacturing reproducibility.
• Versapor acrylic copolymer membranes provide a unique combination of hydrophilicity and mechanical flexibility not available from standard PES or nylon membranes.
• Chemical resistance to common processing agents enables integration of Versapor membranes into devices requiring post-assembly gamma or EtO treatment.
• 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.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. With this in mind, low extractable levels from the filter medium protect the analytical cleanliness of your filtrate, reducing the background interference that complicates trace-level analyses and forces unnecessary repeat measurements. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• 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.
• Cleanroom Monitoring - Used in active air samplers to collect viable particles in cleanrooms for subsequent culture and identification.
• Airborne Metals Analysis - Captures industrial dust for acid digestion and analysis, ensuring accurate monitoring of workplace exposure limits.
• 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.
