Biologix MCE Gridded Membrane Filter Sterile, Mixed Cellulose Esters Membrane Disc Filters, 47mm,0.22um, Hydrophilic Filter Paper for Microbial Limit Testing, Individually Wrapped, Pack of 100

These 47mm MCE membrane filters, made from cellulose acetate and cellulose nitrate, come in 0.22µm and 0.45µm. Grid lines spaced at 3.1mm simplify colony counting without affecting growth, while the smooth, flat surface provides clear observation. With a microbial recovery rate over 90%, they are ideal for microbial limit testing, microbial isolation and culture, liquid clarification, particle detection, and particle removal. Thickness: 115–140µm. Heat stable up to 130°C. Individually sealed without protective paper, each filter stays perfectly flat and ready for immediate use.

• HIGH-QUALITY MCE MEMBRANE: Made from Mixed Cellulose Esters (MCE), composed of cellulose acetate and cellulose nitrate. Biologically inert and widely used for microbiological analysis of water, wastewater, cosmetics, pharmaceuticals, and beverages. Available in 47mm diameter with 0.22µm and 0.45µm pore sizes. Naturally hydrophilic, unsupported membrane with a smooth, flat surface for excellent observation.
• GRID LINES FOR EASY COUNTING: MCE Gridded Membrane Filter Clearly defined grid lines spaced at 3.1mm intervals. Contrasting grids (white-grid-on-black or black-grid-on-white) facilitate colony identification and counting without causing eye fatigue.
• HIGH MICROBIAL RECOVERY: This Mixed Cellulose Esters Membrane Filter Most suitable for microbial limit testing, microbial isolation and culture. Microbial recovery rate exceeds 90%. Membrane thickness of 115-140µm provides an ideal surface for colony development. Also ideal for liquid clarification filtration, particle detection, and particle removal.
• INDIVIDUAL PACKAGE: Each membrane filter is individually packed and sealed. No protective paper is used — the special packaging design keeps each filter perfectly flat, allowing for easy handling and immediate use directly from the pack.
• RELIABLE PERFORMANCE AND HIGH POROSITY: MCE Membrane Filter High porosity allows high filtration rates for gases and liquids, while also providing a large surface area for adsorption and binding. Heat stability up to 130°C.
