Cytiva's Whatman™ 10407172 MicroPlus-41 STL Sterile Gridded Green Cellulose Nitrate Membrane Filter with 3.1mm Black Grid, Pore Size: 0.45µm, Diameter: 5cm (Pack of 400) For use with Cytiva's Whatman™ Membrane-Butler Models 10477100 & 10477110

Whatman™ MicroPlus-41 gridded cellulose nitrate membrane filters are ideal for analytical methods requiring qualitative, enrichment method microorganism counts for the detection of microbial contamination in foods, beverages, pharmaceuticals, cosmetics and other consumer products. Within the qualitative enrichment method, these filters are incubated on a nutrient medium and then the individual colonies can then be evaluated. This method is also suitable for large sample volumes and low microorganism counts. All membranes used for microbiological quality control are tested systematically for bubble point, flow rate, bacterial retention, recovery rate, and sterility to ensure reliable, consistent results. Features and benefits of these membrane filters include high mechanical strength, a high flow rate and individually wrapped sterile packaging. Membrane filters are furnished with a high-contrast, 3.1mm spaced grid. Furnished in dispenser boxes with 100 numbered membrane filters for easy removal and safe handling with the Whatman™ Membrane-Butler. Color: Green wity Black Grid. Retention: 0.45µm, Diameter: 5.0cm. Packaging: 100 Numbered Membranes/Box; 4 Boxes/Case.
