Pall MicroFunnel Filter Funnel w/ Supor Membrane, 0.2um, 100mL, 47mm, Ungridded - 50/Pk - 4806

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Naturally hydrophilic PES accepts aqueous samples instantly while moving large sample volumes through quickly and holds adsorption low to protect captured cells and analytes. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Low protein binding preserves captured organisms and analytes for recovery
• Low extractables keep the filtrate clean for downstream analysis
• Uniform rated pore gives consistent surface retention across the membrane
• 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 across your regulated water, beverage, and environmental monitoring programs.

Hydrophilic

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