Pall MicroFunnel Filter Funnel w/ ME25 Membrane, 0.45um, 300mL, Gridded - 20/Pk - 4815ME

Pall applies its proprietary membrane casting technology, producing precision-rated media for reproducible organism recovery and particulate retention. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. The hydrophilic MCE surface draws aqueous samples through without pre-wetting and holds bacteria larger than the rated pore at the surface. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• Low-extractable cellulose matrix suits standard microbiological methods
• Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
• Uniform rated pore gives consistent retention across the membrane
• Supplied sterile for immediate aseptic microbiological testing
• Gridded membrane formats guide accurate colony counting and orientation

Accurate microbial counts depend on concentrating the whole sample onto one clean membrane surface. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible so each result you release holds up to review.

• Environmental Water QC - Membrane filtration recovers indicator organisms from surface and recreational water for monitoring.
• Beverage Microbiology - Mixed cellulose ester traps yeast and spoilage organisms from beverage samples for plate counts.
• Heterotrophic Plate Count - The membrane concentrates viable organisms from potable water onto a gridded surface for counting.
• Pharmaceutical Bioburden - MCE membranes recover and concentrate microorganisms from process samples for bioburden counts.
• Standard Methods Testing - Hydrophilic cellulose ester suits EPA and Standard Methods membrane filtration microbiology work.
• Coliform Counting - MCE membranes capture organisms on the surface for total coliform and E. coli colony counts in water.
