Laboratory Applications

In laboratories, tungsten is used in several applications, for example:

• High purity sodium tungstate as a reagent in biochemical analysis.
• Sodium metatungstate for the preparation of heavy liquids to be used for the separation of minerals by density in mineralogy or for density gradient centrifugation in biochemical analysis.
• High purity tungsten granules as an accelerator in the determination of carbon and sulphur in metals by combustion in an induction furnace.
