Escherichia coli WDCM 00013 Vitroids™ are Certified Microorganisms Standards (Certified Microbiological Reference Materials), which can be used as quantitative ａnd qualitative control organisms. They contain colony-forming units (CFUs) in the range of 80-130 CFUs 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.

Escherichia coli WDCM 00013 Vitroids^™ are used as reference strains in routine quality control for food, beverage, water, ａnd environmental testing. Additionally, they are excellent for use in method development ａnd validations, as starter cultures, ａnd for use in research studies ａnd educational purposes.
