Hydrochloric acid

Hydrochloric acid in ethanol is used for the microscopical investigation of mycobacteria in sample material of human origin. It can be applied as decolorizing solution.


  • For microscopy
  • Ziehl-neelsen staining


Once stained, the acid fast mycobacteria keep their coloring even after treatment with strong decolorizing solutions as HCl-ethanol. They remain stained red after counterstaining, whereas the microorganisms susceptible to acid take on the color of the counterstain. 1 L of the hydrochloric acid in ethanol is capable of decolorizing up to 500 slides.


The product is registered as IVD / CE product and can be used in diagnostics and laboratory accreditation.
