Pall MicroFunnel Filter Funnel w/ ME25 Membrane, 0.45um, 100mL, Gridded, Individually Bagged - 50/Pk - 4800ME
Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Mixed cellulose ester holds an even pore structure for reproducible recovery and wets aqueous water and beverage samples on contact. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.
Key Characteristics
- Mixed cellulose ester retains microorganisms on the surface for colony counting
- Low-extractable cellulose matrix suits standard microbiological methods
- Gridded membrane formats guide accurate colony counting and orientation
- Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
- Uniform rated pore gives consistent retention across the membrane
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 under the standardized membrane filter methods you report against. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
