General description
High-quality membranes for microbiological quality control
In microbiological QC testing, liquid is first filtered through a membrane, allowing the microorganisms to collect on the surface. The filter is then incubated on a nutrient medium, and individual colonies are evaluated via a microbial contamination test. All Whatman brand membranes used for microbiological quality control are tested systematically in order to ensure the same high quality from batch to batch. Bacterial retention, bubble point, flow rate, recovery rate, and sterility are all tested.
Features and Benefits
- All MicroPlus-21 membrane filters are white with a high-contrast black grid (3.1 mm)
- Designed specifically for microbiological QC
- High mechanical strength and flow rate
- Tested for bubble point, bacterial retention, flow rate, recovery rate, and sterility
- Individually packaged for convenience and sterility
- Type STL provided in dispenser boxes with 100 numbered membrane filters for easy removal and secure handling using Cytiva′s Membrane-Butler
