MicroFunnel Plus Filter Funnel w/ Aseptic Port & Supor Membrane, 100mL, 0.45um, White, Grid, SP
Pall SKU: 4844

Pall MicroFunnel Plus Filter Funnel w/ Supor Membrane, 0.45um, 100mL, 47mm, Gridded, Aseptic Port - 50/Pk - 4844

Pall applies its proprietary membrane casting technology, producing precision-rated media for reproducible organism recovery and particulate retention. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. The PES membrane sustains fast throughput on large aqueous sample volumes while accepting aqueous samples instantly and preserves organisms and analytes for accurate recovery. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• Supplied sterile for immediate aseptic microbiological testing
• Low protein binding preserves captured organisms and analytes for recovery
• Low extractables keep the filtrate clean for downstream analysis
• Hydrophilic surface wets aqueous samples without pre-wetting
• High-flux polyethersulfone speeds filtration of large water and beverage samples

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.

Hydrophilic

• 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.
• 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.
• 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.
