Versapor Acrylic Copolymer 1200 Membrane Disc Filters, 1.2um - 25mm, 100/Pk SKU: 66393

Versapor Membrane Filters - 66393

Engineered for high retention efficiency and superior chemical stability, the Pall 66393 achieves reliable separation results across a broad range of analytical and preparative applications. In addition, acrylic copolymer membrane construction delivers a naturally hydrophilic, mechanically flexible filtration surface with broad compatibility across aqueous and mild organic solutions. On this basis, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• High tensile strength and flexibility allow Versapor membranes to withstand the mechanical stress of roll-to-roll processing and automated handling systems.
• Thermal stability of the membrane material allows safe operation at temperatures up to 88°C without degradation of retention characteristics or dimensional integrity.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Chemical resistance to common processing agents enables integration of Versapor membranes into devices requiring post-assembly gamma or EtO treatment.
• Versapor acrylic copolymer membranes provide a unique combination of hydrophilicity and mechanical flexibility not available from standard PES or nylon membranes.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. For exactly this reason, 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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• 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.
• Fluid Venting Barriers - Integrated into IV spikes to allow air to enter the bottle while preventing the liquid medication from leaking out.
• 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.
• Proteomic Sample Prep - Clarifies viscous lysates prior to mass spectrometry, removing large debris without stripping hydrophobic peptides.
