Pall MicroFunnel Plus Filter Funnel w/ Metricel Black Membrane, 0.8um, 300mL, 47mm, Gridded - 20/Pk - 4819

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. The PES membrane sustains fast throughput on large aqueous sample volumes while holding adsorption low to protect captured cells and wets aqueous samples on contact without pre-wetting. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Supplied sterile for immediate aseptic microbiological testing
• Uniform rated pore gives consistent surface retention across the membrane
• Hydrophilic surface wets aqueous samples without pre-wetting
• Low extractables keep the filtrate clean for downstream analysis

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 under the standardized membrane filter methods you report against.

Hydrophilic

• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
