MicroFunnel Plus Filter Funnel w/ Supor Membrane, 300mL 0.2um White, Grid, SP, Individ. Bagged,20/Pk
Pall SKU: 4857

Pall MicroFunnel Plus Filter Funnel w/ Supor Membrane, 0.2um, 300mL, 47mm, Gridded - 20/Pk - 4857

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. The PES membrane sustains fast throughput on large aqueous sample volumes while holding adsorption low to protect captured cells and accepts aqueous samples instantly. 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
• Supplied sterile for immediate aseptic microbiological testing
• Uniform rated pore gives consistent surface retention across the membrane
• Low protein binding preserves captured organisms and analytes for recovery

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

• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
• 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.
• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
