Pall MicroFunnel Filter Funnel w/ Supor Membrane, 0.2um, 300mL, 47mm, Gridded - 20/Pk - 4818

Pall Corporation produces under ISO quality system controls, with membranes verified for the rated retention that microbiological and gravimetric analysis depend on. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Hydrophilic polyethersulfone wets aqueous samples on contact without pre-wetting while holding adsorption low to protect captured cells and moves large sample volumes through quickly. 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
• 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
• High-flux polyethersulfone speeds filtration of large water and beverage samples

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 from your sample collection through enumeration.

• 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.
• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
