MicroFunnel Plus Filter Funnel w/ ME25Membrane, 100mL,0.45um, White, Gridded
Pall SKU: 4807ME

Pall MicroFunnel Plus Filter Funnel w/ ME25 Membrane, 0.45um, 100mL, Gridded - 50/Pk - 4807ME

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. Naturally hydrophilic MCE accepts aqueous samples instantly for fast filtration 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
• Mixed cellulose ester retains microorganisms on the surface for colony counting
• Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
• Supplied sterile for immediate aseptic microbiological testing
• Uniform rated pore gives consistent retention across the membrane

Dependable contamination monitoring protects the water and beverage lots you clear for release. Membrane filtration of your full sample volume concentrates the organisms you need to detect onto a single surface so the low-level contamination in your samples is concentrated for recovery and counting.

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