METHYL ORANGE ACS GRADE excellent quality manufacturer, exporter and supplier. METHYL ORANGE ACS GRADE is an azo dye which works as a pH indicator.

Colour change 

The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator itself. Recall that pH indicators are not only natural dyes but also weak acids. The dissociation of the weak acid indicator causes the solution to change color.

Specifications :-

   Transition range: pH 3.1 - pH 4.4pink - orange yellow

MAY-GRUNWALD STAIN excellent quality manufacturer, exporter and supplier. May Grunwald's Blood Stains are basic and acidic dyes which induce multiple colours when applied to cells. Methanol acts as a fixative and also as a solvent. The fixative does not allow any further change in the cells and makes them adhere to the glass slide. The basic component of white cells (i.e cytoplasm) is stained by the acidic dye and they are described as eosinophilic or acidophilic. The acidic components (e.g.
