| General description: | Citrobacter freundii CECT® 401 Vitroids™ are Certified Microorganisms Standards (Certified Microbiological Reference Materials) that can be used as quantitative and qualitative control organisms. They contain colony forming units (CFUs) in the range of 130-300 CFU per disc. The technology allows long-term conservation and renders the organisms resistant to temperature changes. They are intended to be used as daily internal quality control organisms. These microorganisms are certified according to ISO/IEC 17025 and produced under reproducible conditions compliant with ISO 17034 using authenticated strains from CECT®. These ready-to-use microbiological controls minimize the need for maintaining control strains in the test laboratory and guarantee the use of an authenticated control culture for every quality control test. Vitroids™ are derived from a traceable culture obtained freeze-dried from CECT®. |
