Quality control is an essential element of a laboratory’s quality assurance system and certified reference materials (CRMs) are necessary for effective quality control. The VITROIDS™ and LENTICULE® discs from Supelco® are specially developed to provide laboratories with the ability to use suitable, ready-to-use microbiological controls for every media quality control test. The Colony forming unit (cfu)-concentrations are designed ensuring that no or only minimal dilution steps are required and are provided under license by National Collection of Type Cultures (NCTC®)/ National Collection of Pathogenic Fungi (NCPF®) and Spanish Type Culture Collection (Colección Española de Cultivos Tipo, CECT®), respectively.
The LENTICULE® and VITROIDS™ discs are manufactured under conditions compliant with ISO 17034 and ISO/IEC 17025. These discs contain defined certified cfu’s with a standard deviation and expanded uncertainty. The discs contain pure cultures of bacteria, yeasts or molds in a solid water-soluble matrix. The certified reference material for microorganisms finds its application in routine quality control for food, beverage, water and environmental testing, for method development and validations and as cultures used in research studies.
