Special Application
1. Mordant. Have great usage in chemical biology, dye for cell and tissue staining, sometimes only dye staining solution does not work. The cells were available at this time, the drug solution and dye binding to tissue processing, staining materials can be the drug solution which is used as mordant. It also refers to the dye by dyeing the fabric on some intermediates used to achieve the purpose of dyeing substances.
2. Catalyst. Change the rate of chemical reaction of reactants without changing the chemical balance, and the mass and chemical properties of itself did not change before and after the occurrence of a substance in a chemical reaction.
3. Stabilizer. Sodium tungstate has excellent thermal stability, superior to the traditional system and lead salts of barium, zinc, cadmium-based stabilizers. Sodium tungstate stabilizer may replace some or all organotin.
