Versapor Acrylic Copolymer 800 Membrane Disc Filters, 0.8um - 25mm, 100/Pk SKU: 66400

Versapor Membrane Filters - 66400

The Pall 66400 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. In addition, controlled pore structure provides consistent airflow and liquid flow characteristics that enable reproducible performance in both filtration and lateral flow applications. Because of this, 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

• 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.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.

Scaling from development to routine production requires membrane consistency at every lot, and the documented specifications provide the reproducibility needed to validate the filtration step once. Specifically, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophilic

• 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.
• Fluid Venting Barriers - Integrated into IV spikes to allow air to enter the bottle while preventing the liquid medication from leaking out.
• 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.
