BiosistoStandard is the answer to your practical microbiological quality issues.

BiosistoStandard is a guide that quickly helps you find the necessary Certified Reference Materials for your quality program. The website also gives you a lot of practical information, Whitepapers, photos, FAQs, Articles that can help you optimize the quality of the analysis. The recommended Certified Reference Materials for performance testing suggestions are a Biosisto interpretation of the ISO 11133 and the corresponding analysis standard. The suggested strain(s) has to be used as a minimum.

Biosisto - Quality in Control

Microbiological laboratories should be able to receive reliable analysis without much overhead. A microbiological analyst must be able to focus on the primary activities, for example analysis of the sample material. Quality control should support the analyst in a logical and simple manner. By using modern information technology, process control and quality assurance are designed smarter and more effective.
