MicroFunnel ST Filter Funnel w/ Supor Membrane, 100mL 0.45um White, UnGrid., SP, 40/Pk of 10 Bag
Pall SKU: 4750

Pall Filter Funnel w/ Supor Membrane, 100mL, 47mm - 40/Pk - 4750

Pall applies its proprietary membrane casting technology, producing precision-rated media for reproducible organism recovery and particulate retention. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. High-flux PES moves large sample volumes through quickly and keeps non-specific binding low for clean recovery. 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
• Low protein binding preserves captured organisms and analytes for recovery
• Supplied sterile for immediate aseptic microbiological testing
• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Low extractables keep the filtrate clean for downstream analysis

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.

• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
• 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.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
