General description

Escherichia coli NCTC 9001 Lenticule^® discs 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 30-120 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 NCTC. These ready-to-use microbiological controls minimize the need to maintain control strains in the test laboratory and guarantee an authenticated control culture for every quality control test.

Lenticule^® discs are prepared from a traceable culture obtained freeze-dried from the National Collection of Type Cultures (NCTC) or National Collection of Pathogenic Fungi (NCPF) and are manufactured by Sigma-Aldrich under license from UK Health Security Agency.

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.
