MicroFunnel ST Filter Funnel w/ Supor Membrane, 100mL, 0.2um, White, Grid, SP, 40/Pk
Pall SKU: 4851

Pall MicroFunnel ST Filter Funnel w/ Supor Membrane, 0.2um, 100mL, Gridded - 40/Pk - 4851

Pall Corporation produces under ISO quality system controls, with membranes verified for the rated retention that microbiological and gravimetric analysis depend on. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. Polyethersulfone delivers high flow that speeds water and beverage filtration and preserves organisms and analytes for accurate recovery. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Uniform rated pore gives consistent surface retention across the membrane
• Low extractables keep the filtrate clean for downstream analysis
• Supplied sterile for immediate aseptic microbiological testing
• Hydrophilic surface wets aqueous samples without pre-wetting

Dependable contamination monitoring protects the water and beverage lots you clear for release. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible so each result you release holds up to review. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

Hydrophilic

• 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.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
• Large-Volume Water QC - Polyethersulfone sustains fast flow to filter large potable-water samples for microbial monitoring.
• 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.
