MicroFunnel Filter Funnel w/ Metricel Black Membrane, 100mL 0.45um, Grid, SP, Individ. Bagged,50/Pk
Pall SKU: 4805

Pall MicroFunnel Filter Funnel w/ Metricel Black Membrane, 0.45um, 100mL, 47mm, Gridded - 50/Pk - 4805

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. Naturally hydrophilic PES accepts aqueous samples instantly while moving large sample volumes through quickly and keeps non-specific binding low for clean recovery. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Low extractables keep the filtrate clean for downstream analysis
• 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

Dependable contamination monitoring protects the water and beverage lots you clear for release. 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

• 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.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
