Cellulose Nitrate (CN) Membrane Filters - 10400114

Engineered for high retention efficiency and superior chemical stability, the 10400114 achieves reliable separation results across a broad range of analytical and preparative applications. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• A > 10 psi pressure rating provides confidence that the device will maintain seal integrity and membrane performance under demanding filtration conditions.
• Autoclavable at 121°C without loss of integrity, cellulose nitrate membranes maintain their rated pore structure and dimensional stability through repeated sterilization cycles.
• Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.
• Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. Low extractable levels in cellulose nitrate membranes mean your blank measurements stay minimal, giving you the confidence that weight changes in gravimetric analysis reflect actual sample content rather than membrane artifacts. 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.

Hydrophilic

• Sediment Collection - Efficiently harvests precipitates from chemical reactions, allowing for the recovery and drying of the solid synthesis product.
• 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.
• Air Particulate Sampling - Traps airborne dust and pollen on a positioned open-face filter disc for subsequent microscopic or chemical analysis.
• Microscopy mounting - Retains microorganisms on a flat surface, allowing for direct staining and enumeration under a high-power microscope.
• Radiometric Counting - Collects radioactive precipitates for scintillation counting, providing a consistent geometry for accurate data measurement.
