Pall MicroFunnel Filter Funnel w/ ME25 Membrane, 0.45um, 100mL, Gridded, Petri Dish Lid - 50/Pk - 4810ME
Quality controls spanning raw membrane casting through final device verification ensure consistent retention performance across Pall production lots. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. Mixed cellulose ester holds an even pore structure for reproducible recovery while drawing aqueous samples through without pre-wetting and captures microorganisms on its surface for direct colony counting. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.
Key Characteristics
- Uniform rated pore gives consistent retention across the membrane
- Hydrophilic surface wets aqueous water and beverage samples without pre-wetting
- Supplied sterile for immediate aseptic microbiological testing
- Low-extractable cellulose matrix suits standard microbiological methods
- Mixed cellulose ester retains microorganisms on the surface for colony counting
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.
