General description

AFB-Color malachite green (oxalate) solution can be used as counter staining for microscopic investigation of mycobacteria. Mycobacteria react acid and alcohol resistant and can keep their red color even after treatment with strong decolorants. Whereas the other microorganisms susceptible to acid take on the blue from the blue counter staining. It fulfills all quality requirements for IVD registration and CE certification.
