Our orange silica gel indicator is not impregnated with cobalt chloride, it is the latest product that can replace the blue silica gel indicator. The composite dyeing agent without pollution to the environment has been successrully adopted during the manufacturing process of the orange silica gel indicator. In this way , it has prevent the cobalt chloride from polluting the environment from the very beginning.

Our Orange silica gel indicators have much more adsorption capacity than that of the blue Indicating silical gel. The orange silica gel Indicator has won unprecedented acknowledgement and praise from the clients since its introduction in European and American markets.
