Pall MicroFunnel ST Filter Funnel w/ ME25 Membrane, 0.45um, 100mL, Ungridded - 40/Pk - 4811ME

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. The hydrophilic MCE surface draws aqueous samples through without pre-wetting while keeping an even pore structure for reproducible recovery and captures microorganisms on its surface for direct colony counting. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

• Gridded membrane formats guide accurate colony counting and orientation
• Supplied sterile for immediate aseptic microbiological testing
• Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
• Mixed cellulose ester retains microorganisms on the surface for colony counting
• Uniform rated pore gives consistent retention across the membrane

Accurate microbial counts depend on concentrating the whole sample onto one clean membrane surface. Membrane filtration of your full sample volume concentrates the organisms you need to detect onto a single surface across your regulated water, beverage, and environmental monitoring programs.

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