Versapor Acrylic Copolymer 1200 Membrane Disc Filters, 1.2um - 293 mm, 25/Pk SKU: 66397

Versapor Membrane Filters - 66397

Precision-manufactured Hydrophilic membrane with a verified 1.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Uniform membrane thickness and dimensional stability maintain consistent device-to-device performance in high-volume manufacturing of membrane-based diagnostic products. In effect, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Stable performance at operating temperatures reaching 88°C ensures the membrane handles heated applications without pore distortion or structural compromise.
• 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.
• Versapor acrylic copolymer membranes provide a unique combination of hydrophilicity and mechanical flexibility not available from standard PES or nylon membranes.

Air monitoring and stack emissions sampling demand a filter medium that withstands the conditions at your collection point. The material properties above define that operating envelope. In this context, consistent manufacturing means the filtration performance you observe during initial evaluation repeats on every subsequent unit, supporting the reproducibility your quality system requires. 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.
• Microplastic Counting - Provides a high-contrast background for identifying colored microplastics in environmental water or sand extracts.
• 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.
• Proteomic Sample Prep - Clarifies viscous lysates prior to mass spectrometry, removing large debris without stripping hydrophobic peptides.
• Cleanroom Monitoring - Used in active air samplers to collect viable particles in cleanrooms for subsequent culture and identification.
