MicroFunnel ST Filter Funnel w/ Supor Membrane, 300mL, 0.2um, White, UnGrid., SP, Bags of 5, 20/Pk
Pall SKU: 4853

Pall MicroFunnel ST Filter Funnel w/ Supor Membrane, 0.2um, 300mL, 47mm, Ungridded - 20/Pk - 4853

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. The PES surface keeps non-specific binding low for clean recovery while accepting aqueous samples instantly 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

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

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

• 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.
• Large-Volume Water QC - Polyethersulfone sustains fast flow to filter large potable-water samples for microbial monitoring.
• 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.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
