NCIMB supplies a range of quality control (QC) strains with guaranteed traceability.
Our QC range includes Candida albicans, Aspergillus brassiliensis and Saccharomyces cerevisiae in addition to 29 commonly required bacterial strains. All of NCIMB’s QC strains are certified first generation reference strains produced to ISO 9001:2015 standards.
As curators of the UK’s National Collection of Industrial Food and Marine Bacteria, we can guarantee traceability, and provide strains equivalent to other culture collections where available. By using first generation strains in our QC products, we minimise the risk of genetic drift, and help our customers to work to the highest quality control standards.
QC strain formats
Ampoules and vials
NCIMB’s glass ampoule and screw top vial QC products contain a strip of filter paper impregnated with freeze dried culture, giving a convenient format for single use procedures such as quality assurance testing of culture media.
Once the ampoule or vial has been opened, the strip can be dropped directly into or onto the appropriate medium, reducing risk of contamination. There are no expert handling requirements for this format and shelf life is considerably longer than for vacuum packaged gelatine-based products.
Our contract freeze drying service is available for preservation of customer strains, such as isolates obtained from environmental monitoring programmes.
All strains listed are available as screw-top bottles or glass ampoules.
All strains and formats are available as packs of five for £80 plus postage and packaging costs.
