Pall MicroFunnel Plus Filter Funnel w/ Supor Membrane, 0.45um, 100mL, Gridded - 40/Pk - 4859

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. Naturally hydrophilic PES accepts aqueous samples instantly while keeping non-specific binding low for clean recovery and delivers high flow that speeds water and beverage filtration. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

• Uniform rated pore gives consistent surface retention across the membrane
• Low extractables keep the filtrate clean for downstream analysis
• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Supplied sterile for immediate aseptic microbiological testing
• Low protein binding preserves captured organisms and analytes for recovery

Accurate microbial counts depend on concentrating the whole sample onto one clean membrane surface. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible so each result you release holds up to review.

Hydrophilic

• 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.
• 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.
• 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.
