Pall MicroFunnel Filter Funnel w/ Supor Membrane, 0.45um, 300mL, 47mm, Gridded - 20/Pk - 4828

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. Low-protein-binding polyethersulfone preserves organisms and analytes for accurate recovery while sustaining fast throughput on large aqueous volumes and wets aqueous samples on contact without pre-wetting. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• 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
• Low protein binding preserves captured organisms and analytes for recovery
• High-flux polyethersulfone speeds filtration of large water and beverage samples

Dependable contamination monitoring protects the water and beverage lots you clear for release. 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

• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
• Large-Volume Water QC - Polyethersulfone sustains fast flow to filter large potable-water samples for microbial monitoring.
• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
