Pall MicroFunnel Filter Funnel w/ ME25 Membrane, 0.45um, 100mL, Gridded - 200/Pk - 4804ME

Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. Hydrophilic cellulose ester wets aqueous water and beverage samples on contact while sustaining consistent pore sizing across the disc and captures microorganisms on its surface for direct colony counting. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

• Gridded membrane formats guide accurate colony counting and orientation
• Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
• Supplied sterile for immediate aseptic microbiological testing
• Mixed cellulose ester retains microorganisms on the surface for colony counting
• Low-extractable cellulose matrix suits standard microbiological methods

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 so the low-level contamination in your samples is concentrated for recovery and 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.
• 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.
• 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.
