QC microorganisms – only 3 passages from the original seed lot

Oxoid Quanti-Cult Plus QC microorganisms are the ideal solutions for the performance qualification of culture media within the pharmaceutical laboratory. Derived directly from ATCC® strains, each ready-to-use vial is just 3 passages from the original seed lot – well within pharmacopoeial requirements – ensuring reliable and consistent phenotypic characteristics.

Each Oxoid Quanti-Cult Plus pack contains 10 vials of preserved microorganisms, complete with predispensed rehydration fluid, and can be stored conveniently in the fridge (2-8°), both before rehydration and for up to 8 hours after rehydration. Individual vials deliver consistent counts of <100 CFU in 10 inocula of 0.1mL. This ensures reproducible results, eliminating the inaccuracies that are inherent in performing serial dilutions, and helps to standardize procedures among all staff.

Mean counts are provided for each batch and are included in every Oxoid Quanti-Cult Plus pack, along with certificates of analysis and instructions for use This ensures that you have all the information you need conveniently to hand, while easily transferable labels ensure fast and accurate documentation.

By eliminating the bench work associated with serial dilutions and the maintenance of stock cultures, Oxoid Quanti-Cult Plus is not only accurate and reliable, but it is also time saving and cost effective. With no need for sharps and no need for freezer storage, this is a safe and convenient option for every laboratory.
