Belkhim OJSC offers phenolphthalein and other chemical indicators: bengale red, dimethyl yellow, dithizone, cupferron, malachite green, methylene blue, methyl red and orange, pyrogallol, chrome dark blue, erychrome black. Introduction of chemical indicators into the test solution allows for establishing chemical reaction end point or pH of the solution by easily remarkable sign (discoloration, turbidity appearance or disappearance, luminescence, etc.). Chemical indicators are primarily used in titrimetric analysis for establishing equivalence point (titration end point).
