Membrane Solutions Mixed Cellulose Ester (MCE) Gridded Membrane Filter — 47 mm, 0.45 µm

Title Mixed Cellulose Ester (MCE) Sterile Gridded Membrane Filter — Hydrophilic MCE Membrane for Microbiological Analysis

Short description Hydrophilic Mixed Cellulose Ester (MCE) membrane filter designed for reliable microbiological analysis of water, wastewater, cosmetics, pharmaceuticals, and beverages. Sterile gridded membrane for accurate colony counting and sterility testing.

Key features - Composition: Mixed cellulose acetate and cellulose nitrate for high biological inertness.
- Naturally hydrophilic, without support layer — ready for aqueous filtration.
- Sterile gridded membrane filter with contrasting grid lines spaced at 3.1 mm to simplify colony counting.
- Grid lines tested to assure freedom from grid line inhibition.
- High porosity for fast filtration rates and a large surface area for adsorption and binding.
- Sterilized by 25 kGy gamma radiation and individually sealed to maintain sterility.
- Individual package placement on a band keeps each membrane flat and ready for immediate use.
- Quality assured: ISO 9001 certified and meets ISO 7704 requirements.

Benefits - Improves accuracy of colony counting and sterility testing with clear, contrasting grid lines.
- Speeds workflow and reduces handling time through flat, ready-to-use, individually packaged membranes.
- High porosity increases throughput for filtration of water, wastewater, cosmetics, pharmaceuticals, and beverages.
- Sterile packaging minimizes contamination risk and reduces rework.

Typical applications - Microbiological analysis and colony counting for drinking water and wastewater testing.
- Sterility testing and QC in pharmaceutical and cosmetic manufacturing.
- Microbial screening and quality control in beverage production.
- Laboratory membrane filtration assays and environmental monitoring.

Packaging and sterility - Each membrane disc is sterile-sealed in an individual package and sterilized by 25 kGy gamma irradiation.
- Note: The product is supplied sterile following irradiation processing and is not capable of on-site sterilization.
