Versapor Acrylic Copolymer 3000 Membrane Disc Filters, 3 um - 142mm, 25/Pk SKU: 66389

Versapor Membrane Filters - 66389

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66389 provides the filtration consistency that method validation demands. At its core, uniform membrane thickness and dimensional stability maintain consistent device-to-device performance in high-volume manufacturing of membrane-based diagnostic products. In practice, lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Chemical resistance to common processing agents enables integration of Versapor membranes into devices requiring post-assembly gamma or EtO treatment.
• 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.
• 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.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. Here, low extractable levels from the filter medium protect the analytical cleanliness of your filtrate, reducing the background interference that complicates trace-level analyses and forces unnecessary repeat measurements. 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.
• Fluid Venting Barriers - Integrated into IV spikes to allow air to enter the bottle while preventing the liquid medication from leaking out.
• 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.
• 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.
