Cellulose Nitrate (CN) Membrane Filters - 10401316

The 10401316 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention across the full operating range. 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

• 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.
• Maximum operating temperature of 121°C accommodates warm sample filtration and elevated-temperature processes that exceed the limits of standard devices.
• Pressure-rated to > 10 psi, the device maintains its structural and sealing integrity through the pressure spikes encountered during syringe-driven filtration.
• Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.
• Autoclavable at 121°C without loss of integrity, cellulose nitrate membranes maintain their rated pore structure and dimensional stability through repeated sterilization cycles.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. The narrow pore size distribution of cellulose nitrate membranes ensures your retention data is consistent across batches, reducing the inter-sample variability that complicates quantitative particulate and microbiological analyses. If your laboratory requires volume pricing, custom packaging configurations, or scheduled delivery programs, the Tisch Scientific sales team can structure a supply arrangement matched to your consumption rate.

Hydrophilic

• Air Particulate Sampling - Traps airborne dust and pollen on a positioned open-face filter disc for subsequent microscopic or chemical analysis.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
• Stack Pre-filtration - Acts as a spacer or depth layer in multi-tier filtration stacks to extend the life of the final downstream membrane.
• Quality Control Testing - Serves as a standard check filter for routine batch purity tests, verifying the absence of visible physical contaminants.
• Vacuum Clarification - Utilized in Buchner funnels to rapidly remove particulates from large-volume batches of non-critical laboratory buffers.
