Gridded MCE Membrane Filter, Sterile, Hydrophilic - 0.45µm, 47mm, Water & Air Analysis, 100/Pk SKU: LE-045SG-047-C

Featuring sterile mixed cellulose ester (MCE) membrane technology with integrated grid markings delivering enhanced colony counting accuracy for microbiological water analysis and air monitoring applications. The 0.45µm pore configuration provides precise bacterial retention while maintaining consistent flow characteristics for EPA-compliant microbiological testing protocols¹. Hydrophilic surface chemistry optimizes aqueous sample processing with uniform wetting characteristics, accelerating filtration cycles during high-volume water quality assessments.

• Sterile construction eliminates pre-sterilization requirements and ensures contamination-free sample processing protocols
• Integrated grid pattern facilitates accurate colony enumeration and reduces counting errors during microbiological analysis
• Mixed cellulose acetate and cellulose nitrate composition delivers superior surface uniformity compared to pure nitrocellulose membranes
• Hydrophilic surface treatment ensures complete and uniform wetting for consistent filtration performance across diverse water matrices
• Biologically inert construction prevents interference with microbial growth during incubation and analysis procedures

• 47mm diameter accommodates standard filter holders and sampling equipment for water quality and environmental monitoring
• Enhanced durability with reduced cracking and fracturing compared to traditional cellulose nitrate membranes
• Pure membrane surface requires no additional smoothing treatments or surfactants that could interfere with analysis
• NIOSH-compliant construction suitable for airborne metals and asbestos monitoring applications²
• White membrane background provides optimal contrast for microscopic examination and colony identification

LE-045SG-047-C filters achieve validated performance for microbiological analysis of potable, waste, process, and natural waters using the Membrane Filter Technique referenced in Standard Methods for the Examination of Water and Wastewater³. Outstanding compatibility with EPA microbiological monitoring methods¹ transforms these gridded membranes into reference-grade media for your critical environmental testing applications. The integrated grid system maximizes counting accuracy and analytical throughput, providing performance assurance for water quality laboratories demanding both precision and regulatory compliance in their microbiological testing protocols.
