MicroFunnel Plus Filter Funnel w/ Supor Membrane, 100mL 0.45um White, Grid, SP, Individ. Bag 50/Pk
Pall SKU: 4823

Pall MicroFunnel Plus Filter Funnel w/ Supor Membrane, 0.45um, 100mL, 47mm, Gridded - 50/Pk - 4823

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. 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 and holds adsorption low to protect captured cells and analytes. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

• Hydrophilic surface wets aqueous samples without pre-wetting
• Uniform rated pore gives consistent surface retention across the membrane
• Low protein binding preserves captured organisms and analytes for recovery
• Low extractables keep the filtrate clean for downstream analysis
• Supplied sterile for immediate aseptic microbiological testing

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.

Hydrophilic

• 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.
• 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.
• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
