Cellulose Nitrate (CN) Membrane Filters - 10402012
The Whatman 10402012 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Consequently, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.
Material Specifications
- Naturally hydrophilic and compatible with aqueous solutions, cellulose nitrate delivers high flow rates and rapid wet-out without requiring pre-conditioning or surfactant treatment.
- Dissolves completely in specific organic solvents, enabling full recovery of captured particles from the membrane surface for downstream gravimetric, chemical, or spectroscopic analysis.
- Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
- Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.
- Cellulose nitrate membranes feature a narrow pore size distribution and low extractable levels, providing the controlled retention characteristics required for gravimetric and particulate analysis.
When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. Cellulose nitrate's dimensional stability through autoclaving at 121°C means your membranes maintain their rated pore structure and physical dimensions from pre-sterilization through final analysis, supporting method reproducibility. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
