MicroFunnel ST Filter Funnel w/ Supor Membrane, 300mL 0.45um White, UnGrid., SP, 20/Pk of 5 Bag
Pall SKU: 4751

Pall MicroFunnel ST Filter Funnel w/ Supor Membrane, 0.45um, 300mL, 47mm, Ungridded - 20/Pk - 4751

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. Polyethersulfone holds adsorption low to protect captured cells and analytes while drawing aqueous samples through readily and moves large sample volumes through quickly. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

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

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 for the regulated microbial enumeration your methods require. Ask the Tisch Scientific team about blanket-order pricing and quality documentation for your routine filtration needs.

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.
• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
