      Featuring sterile mixed cellulose ester (MCE) membrane technology delivering exceptional flow rates and high bacterial recovery for critical microbiological analysis applications. Biologically inert mixtures of cellulose acetate and cellulose nitrate result in membranes with a smoother and more uniform surface than pure nitrocellulose, while integrated grid lines facilitate precise colony counting without eye fatigue. The 0.45µm pore structure provides reliable retention of bacteria and particulates while maintaining superior flow characteristics for water quality testing, air monitoring, and pharmaceutical applications requiring validated sterile filtration protocols. Key MCE Membrane Characteristics • Smoother and more uniform surface than pure nitrocellulose with less cracking and fracturing than traditional CN membranes ensures consistent filtration performance • Grid lines with nontoxic ink completely free from bacterial growth inhibitors enhance colony counting accuracy without affecting bacterial development • High bacterial recovery rates and superior flow rates optimize processing efficiency for high-volume microbiological testing applications • Pure surface with no additional smoothing treatment or surfactants maintains analytical integrity for critical trace analysis protocols • Pre-sterilized and individually packed configuration eliminates contamination risk while ensuring single-use sterility for pharmaceutical and clinical applications Key Construction Characteristics • Gridded pattern with clearly defined lines spaced at 3.1mm intervals facilitates precise manual colony counting and reduces counting errors • Gravimetric analysis residue of less than 0.045% initial weight with hydrophilic wetting agent extractable level below 4% ensures analytical accuracy • Standard 47mm diameter accommodates EPA microbiological methods1 and universal filter holder configurations for regulatory compliance applications • Mixed cellulose ester construction designated suitable for asbestos counting meets NIOSH requirements2 for airborne metals and fiber monitoring protocols • Fast flow rates with high protein binding capacity and great thermal stability make these filters essential for environmental and biological laboratory applications LE-045SG-047-D filters achieve outstanding bacterial recovery rates exceeding industry standards, accelerating your microbiological testing cycles while maintaining analytical precision during extended monitoring campaigns. Certified for microbiological analysis of potable, waste, process, and natural waters in accordance with Standard Methods for the Examination of Water and Wastewater3, these sterile gridded membranes deliver validated performance for your critical water quality monitoring, pharmaceutical testing, and air analysis applications demanding both regulatory compliance and exceptional counting accuracy.
