MicroFunnel Filter Funnel w/ Supor Membrane, 100mL 0.45um White, Grid, SP, Individ. Bagged, 50/Pk
Pall SKU: 4852

Pall MicroFunnel Filter Funnel w/ Supor Membrane, 0.45um, 100mL, 47mm, Gridded - 50/Pk - 4852

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. Polyethersulfone delivers high flow that speeds water and beverage filtration and accepts aqueous samples instantly. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

• Uniform rated pore gives consistent surface retention across the membrane
• Supplied sterile for immediate aseptic microbiological testing
• Hydrophilic surface wets aqueous samples without pre-wetting
• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Low protein binding preserves captured organisms and analytes for recovery

Confidence in your microbial results starts with capturing the organisms from your whole sample onto a single membrane. Membrane filtration of your full sample volume concentrates the organisms you need to detect onto a single surface so the low-level contamination in your samples is concentrated for recovery and counting.

Hydrophilic

• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
• Large-Volume Water QC - Polyethersulfone sustains fast flow to filter large potable-water samples for microbial monitoring.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
