What is the difference between accreditated and not accreditated CRM?

Biosisto produces certified microbiological reference materials. The certified materials have a subdivision into four types of material.
The difference between the types of certified material is reflected in the strain’s metrological traceability, the property value’s determination, and whether it is part of the flex-scope of accreditation by the Dutch Accreditation Council.

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.
