Qualitative lyophilised pellets delivering a certified viable inoculum of more than 10³ CFU per vial. VerisQ WC is designed for applications where confirmed growth is required rather than a precise enumerated count — including positive controls for sterility testing, qualitative growth promotion confirmation, specified organism presence/absence testing, and preparation of working stock cultures. Each pellet reconstitutes in seconds to provide a ready-to-use viable suspension of authenticated compendial organisms.
