The Charm Blue Yellow II Test is a microbial inhibition assay, which detects inhibitors in milk. The test consists of a single service well that contains pre-measured bacterial spores,* media, and a pH indicator.  

Reagents are unit dosed and compartmentalized to ensure uniformity. This eliminates reagent transfer steps and prevents inadvertent contamination and reagent loss.
