Emichem offers the product Fluorescein Potassium: CAS # 6417-85-2 of highest purity. The product is also known as Acid Yellow 73 (Potassium Salt). Heavy metals content is all below prescribed limit. In 2003, we understood the demands of buyers for Highly Purified Salt- Free Dyestuffs for Inkjet Ink manufacturing. These Dyes are meticulously manufactured, using different filtration techniques and Reverse Osmosis. We use Specific Ion Exchange Resins and also chemical treatment is adopted to minimise the heavy metal content. The global demand for Digital Textile Printing has helped us grow in the field of Highly Purified Dyestuffs.
