Cellulose Nitrate (CN) Membrane Filters - 10400206

The 10400206 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. 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

• Stable performance at operating temperatures reaching 80°C ensures the device handles heated applications without membrane distortion or housing softening.
• A > 10 psi pressure rating provides confidence that the device will maintain seal integrity and membrane performance under demanding filtration conditions.
• High protein binding capacity makes cellulose nitrate the preferred membrane for Western blotting, dot blotting, and nucleic acid immobilization techniques that rely on efficient surface adsorption.
• Cellulose nitrate membranes feature a narrow pore size distribution and low extractable levels, providing the controlled retention characteristics required for gravimetric and particulate analysis.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. The high protein binding capacity of cellulose nitrate provides the strong surface adsorption that your blotting protocols depend on, immobilizing target molecules efficiently for detection with minimal wash-off during subsequent processing steps. For detailed specification sheets, validation documentation, or technical guidance on membrane selection for your specific application, the Tisch Scientific team is available to support your evaluation.

• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• Air Particulate Sampling - Traps airborne dust and pollen on a positioned open-face filter disc for subsequent microscopic or chemical analysis.
• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
• Gravimetric Analysis - Captures total suspended solids from liquid samples on a weighed disc, ensuring accurate mass measurements for reporting.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
