Pall MicroFunnel Plus Filter Funnel w/ Metricel Black Membrane, 0.45um, 300mL, 47mm, Gridded - 20/Pk - 4817

Pall Corporation produces under ISO quality system controls, with membranes verified for the rated retention that microbiological and gravimetric analysis depend on. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. High-flux PES moves large sample volumes through quickly while preserving organisms and analytes through low protein binding and draws aqueous samples through readily. 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
• Hydrophilic surface wets aqueous samples without pre-wetting
• Low extractables keep the filtrate clean for downstream analysis
• Supplied sterile for immediate aseptic microbiological testing
• Uniform rated pore gives consistent surface retention across the membrane

Confidence in your microbial results starts with capturing the organisms from your whole sample onto a single membrane. Membrane filtration of your full sample volume concentrates the organisms you need to detect onto a single surface for the regulated microbial enumeration your methods require.

Hydrophilic

• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
