詳細
To protect the consumer, the absence of microbial contamination in foods and beverages, pharmaceuticals and cosmetics must be assured.
In these products the microorganism counts are very low and are therefore determined quantitatively via enrichment methods. Production processes are monitored continuously at their critical points (tanks, pipelines, filling units) as are the finished products. The membrane filtration method is the optimal analytical method for doing this.
Method:
The liquid is filtered through a membrane. The microorganisms collect on the membrane surface. The filter is incubated on a nutrient medium and the individual colonies can then be evaluated. The method is also suitable for large sample volumes and low microorganism counts.
Reliability:
The quality control and product design of our membrane filters are strictly controlled and offer users significant advantages.
Test parameters:
All membranes used for microbiological quality control are tested systematically in order to ensure the same high quality from batch to batch. Parameters tested are bubble point, flow rate, bacterial retention, recovery rate, and sterility.
