MicroFunnel Filter Funnel w/ Supor Membrane, 100mL 0.2um White, Grid, SP, Individ. Bagged, 50/Pk
Pall SKU: 4803

Pall MicroFunnel Filter Funnel w/ Supor Membrane, 0.2um, 100mL, 47mm, Gridded - 50/Pk - 4803

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. High-flux PES moves large sample volumes through quickly while preserving organisms and analytes through low protein binding and wets aqueous samples on contact without pre-wetting. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

• Supplied sterile for immediate aseptic microbiological testing
• Low protein binding preserves captured organisms and analytes for recovery
• Hydrophilic surface wets aqueous samples without pre-wetting
• Low extractables keep the filtrate clean for downstream analysis
• 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.

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.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
• 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.
