一般描述

Clostridium perfringens NCTC 13170 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 for maintaining control strains in the test laboratory ａnd guarantee the use of 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.
