Pall MicroFunnel ST Filter Funnel w/ ME25 Membrane, 0.45um, 300mL, Ungridded - 20/Pk - 4812ME

Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Cellulose ester holds bacteria larger than the rated pore at the surface and wets aqueous water and beverage samples on contact. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

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

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 for the regulated microbial enumeration your methods require.

• 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.
• Heterotrophic Plate Count - The membrane concentrates viable organisms from potable water onto a gridded surface for counting.
• 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.
• Coliform Counting - MCE membranes capture organisms on the surface for total coliform and E. coli colony counts in water.
