Beschreibung

General description

Listeria monocytogenes serovar 1/2a WDCM 00109 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 1,000-10,000 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^®.

We are committed to bringing you Greener Alternative Products. This product is a Design for Sustainability (DfS) developed product, which belongs to one of our four categories of greener alternatives. Click here to view its DfS scorecard.
