Product Description
The Whatman ME29 ST Membrane Filter | 10400772 is a premium-quality sterile mixed cellulose ester (MCE) membrane filter designed for high-flow laboratory filtration, microbiological testing, and analytical applications. Featuring a 3.0 µm pore size and 50 mm diameter, this hydrophilic membrane provides excellent particle retention, high dirt-loading capacity, and consistent filtration performance, making it suitable for laboratories requiring reliable and reproducible results.
Manufactured from a carefully engineered blend of cellulose nitrate and cellulose acetate, the Whatman ME29 ST membrane offers excellent mechanical strength, biological inertness, and thermal stability. Its uniform microporous structure ensures high flow rates while maintaining effective particle capture. The sterile membrane is ideal for microbiology laboratories, pharmaceutical quality control, environmental monitoring, biotechnology research, food and beverage testing, and educational institutions.
The membrane’s high internal surface area enhances adsorption efficiency, while its surfactant-free construction helps preserve sample integrity by minimizing contamination. Supplied sterile in packs of 100, the filter is ready for immediate use and is compatible with standard 50 mm membrane filtration assemblies. Its excellent contrast also simplifies particle detection during laboratory analysis.
