MicroFunnel Filter Funnel w/ ME25Membrane, 100mL,0.45um, White, Gridded, Sterile
Pall SKU: 4801ME

Pall MicroFunnel Filter Funnel w/ ME25 Membrane, 0.45um, 100mL, Gridded, Bulk Pack - 50/Pk - 4801ME

Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. Cellulose ester holds bacteria larger than the rated pore at the surface while holding a uniform rated pore across the membrane and wets aqueous water and beverage samples on contact. 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
• Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
• Low-extractable cellulose matrix suits standard microbiological methods
• Uniform rated pore gives consistent retention across the membrane
• Mixed cellulose ester retains microorganisms on the surface for colony counting

Dependable contamination monitoring protects the water and beverage lots you clear for release. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible so each result you release holds up to review.

• 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.
• 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.
