FAQs

What is Bacillus cereus WDCM 00001 Vitroids used for?

Bacillus cereus WDCM 00001 Vitroids™ is a certified microbiological reference material used for quantitative and qualitative quality control in routine laboratory testing. It serves as a control organism in food, beverage, water, and environmental testing applications, supporting validation and proficiency testing programs.

What is the certified concentration per disc?

Each freeze-dried disc contains between 1,000 and 10,000 colony forming units. This defined range supports consistent performance in quality control procedures and allows laboratories to use the material as a standardized internal control without additional dilution or preparation steps.

How is this reference material produced and certified?

This product is manufactured under ISO 17034 and certified according to ISO/IEC 17025 requirements. It is derived from an authenticated, traceable CECT® strain and supplied with a comprehensive certificate of analysis, ensuring documented accuracy, reproducibility, and compliance for regulated laboratory environments.

How is the product stored and what is its shelf life?

The discs must be stored at −20°C to maintain stability and certified performance. When kept at this temperature, the product typically has a shelf life of two to three years, with the specific expiration date clearly stated on the product label.

Is the product ready to use upon receipt?

Yes, the freeze-dried discs are ready to use and require only brief rehydration, typically within ten minutes. No dilution, recovery period, or pre-enrichment step is required, simplifying workflow and reducing the need to maintain in-house stock cultures.
