Versapor Acrylic Copolymer 800 Membrane Disc Filters, 0.8um - 37mm, 100/Pk SKU: 66331

Versapor Membrane Filters - 66331

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66331 provides the filtration consistency that method validation demands. High tensile strength and tear resistance support automated handling, die-cutting, and roll-to-roll conversion processes used in diagnostic device manufacturing. Taken together, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Stable performance at operating temperatures reaching 88°C ensures the membrane handles heated applications without pore distortion or structural compromise.
• Controlled porosity delivers consistent flow rates and predictable retention characteristics across production lots for device manufacturing reproducibility.
• 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.

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 documented retention specifications of this device ensure that your filtrate meets the particulate cleanliness requirements of your downstream analytical or process step without additional verification. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophilic

• Airborne Metals Analysis - Captures industrial dust for acid digestion and analysis, ensuring accurate monitoring of workplace exposure limits.
• Microplastic Counting - Provides a high-contrast background for identifying colored microplastics in environmental water or sand extracts.
• Fluid Venting Barriers - Integrated into IV spikes to allow air to enter the bottle while preventing the liquid medication from leaking out.
• 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.
• Proteomic Sample Prep - Clarifies viscous lysates prior to mass spectrometry, removing large debris without stripping hydrophobic peptides.
