Blue Yellow II
Charm Blue Yellow II is a microbial inhibition assay that detects inhibitors, such as antibiotics – the most common inhibitors found in raw milk. The Charm Blue Yellow II has achieved the Charm Gold Standard by establishing a new benchmark in sensitivity by detecting many antimicrobial drugs at or below EU MRLs (Maximum Residue Limits). It is designed for high volume screening of raw commingled and ultra-pasteurized cow milk.


     • Broadest detection for antibiotics and other antimicrobials 
     • Detects many drugs at or near EU MRLs
     • Easy: Just add milk and incubate
     • Results in less than 3 hours
     • Ideal for large volume testing
