Cellulose Nitrate (CN) Membrane Filters - 7182-001
Engineered for high retention efficiency and superior chemical stability, the Whatman 7182-001 achieves reliable separation results across a broad range of analytical and preparative applications. At its core, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. 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
- Surface retention characteristics allow captured particles and microorganisms to remain on the membrane face, supporting direct microscopic examination and physical recovery of collected material.
- Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
- 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.
- 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.
Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. For applications like these, 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.
