Selective · Differential · Reference Standards. Built for labs that need certainty, not guesses.
Our chromogenic media line provides selective and differential detection of specific microorganisms with clear, enzyme-based color reactions for direct visual identification — no additional confirmation steps required for most targets.
Every batch of our products ships with certified QC reference materials. But we also offer standalone QC materials for labs that need certified reference standards for method validation, proficiency testing, and accreditation documentation.
