Versapor Acrylic Copolymer 1200 Membrane Disc Filters, 1.2um - 47mm, 100/Pk SKU: 66394

Versapor Membrane Filters - 66394

The Pall 66394 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Engineered for demanding applications, controlled pore structure provides consistent airflow and liquid flow characteristics that enable reproducible performance in both filtration and lateral flow applications. As designed, 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

• 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.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 88°C, supporting heated filtration protocols.
• High tensile strength and flexibility allow Versapor membranes to withstand the mechanical stress of roll-to-roll processing and automated handling systems.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.

Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. 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.

• 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.
• 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.
• Airborne Metals Analysis - Captures industrial dust for acid digestion and analysis, ensuring accurate monitoring of workplace exposure limits.
