Pall MicroFunnel Plus Filter Funnel w/ Supor Membrane, 0.2um, 100mL, 37mm, Gridded - 50/Pk - 4809

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. Polyethersulfone delivers high flow that speeds water and beverage filtration while drawing aqueous samples through readily and keeps non-specific binding low for clean recovery. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

• Low extractables keep the filtrate clean for downstream analysis
• Hydrophilic surface wets aqueous samples without pre-wetting
• Supplied sterile for immediate aseptic microbiological testing
• Low protein binding preserves captured organisms and analytes for recovery
• Uniform rated pore gives consistent surface retention across the membrane

Accurate microbial counts depend on concentrating the whole sample onto one clean membrane surface. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible from your sample collection through enumeration.

Hydrophilic

• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
• Large-Volume Water QC - Polyethersulfone sustains fast flow to filter large potable-water samples for microbial monitoring.
• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
