Sterile MicroPlus -21 STL Membrane, w/ 3.1mm Black Grid for Membrane-Butler, 0.45um, 47mm SKU: 10407713

Cellulose Nitrate (CN) Membrane Filters - 10407713

The Whatman 10407713 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. At its core, precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention across the full operating range. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Autoclavable at 121°C without loss of integrity, cellulose nitrate membranes maintain their rated pore structure and dimensional stability through repeated sterilization cycles.
• Pre-sterilized packaging eliminates the need for in-house autoclaving, reducing preparation time and ensuring consistent sterility from lot to lot.
• Cellulose nitrate membranes feature a narrow pore size distribution and low extractable levels, providing the controlled retention characteristics required for gravimetric and particulate analysis.
• 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.
• Naturally hydrophilic and compatible with aqueous solutions, cellulose nitrate delivers high flow rates and rapid wet-out without requiring pre-conditioning or surfactant treatment.

Air monitoring and stack emissions sampling demand a filter medium that withstands the thermal and chemical conditions at your collection point — the material properties described above define the operating envelope for your application. In this context, surface retention on cellulose nitrate keeps captured particles and microorganisms on the membrane face where they remain accessible for direct microscopic examination, colony counting, and physical recovery without sectioning or dissolution. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Aerosol Analysis - Low tare weight and acid digestibility enable chemical characterization of airborne particulates from air sampling.
• Colony Enumeration - Gridded surface variants facilitate accurate plate counting of captured microorganisms under standard magnification.
• Environmental Compliance - Documented retention characteristics at standard pore ratings support reproducibility in regulated testing programs.
• Gravimetric Particulate Analysis - Dissolves in organic solvents for complete particle recovery and accurate weight-based quantification.
• Bioburden Monitoring - Surface retention keeps captured organisms accessible for direct incubation and enumeration without transfer steps.
• Microscopy Examination - Particles remain on the membrane surface for direct visual inspection, supporting identification and classification.
