Pall MicroFunnel Plus Filter Funnel w/ ME25 Membrane, 0.45um, 300mL, Gridded - 20/Pk - 4829ME

Pall Corporation produces under ISO quality system controls, with membranes verified for the rated retention that microbiological and gravimetric analysis depend on. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. The MCE membrane retains target organisms at the face for enumeration and gives consistent retention across the whole membrane. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

• Supplied sterile for immediate aseptic microbiological testing
• 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
• Hydrophilic surface wets aqueous water and beverage samples without pre-wetting

Confidence in your microbial results starts with capturing the organisms from your whole sample onto a single membrane. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible from your sample collection through enumeration.

Hydrophilic

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