Product Description
CAS 11130-12-4 borax pentahydrate borax decahydrate borax powder 99.9 price
A. Household Products Borax is used in a variety of household laundry and cleaning products. Some tooth bleaching formulas also contain borax. B. Buffers Sodium borate is used in biochemical and chemical laboratories to prepare buffers such as for DNA gel electrophoresis such as TBE or the newer SB buffer or BBS (Borate Buffered Saline) during coating . Borate buffer (typically pH 8) is also used as a preferential equilibration solution in DMP-based crosslinking reactions. C. Flux A mixture of borax and ammonium chloride is used as a flux when welding steel. It lowers the melting point of unwanted iron oxide (scale) allowing it to drain away. Borax is also mixed with water and used as a flux when soldering jewelry metals such as gold or silver. It allows molten solder to flow evenly over problematic joints. Borax is also a good flux for "pre-tinning" tungsten and zinc - making tungsten solderable. D. Small-scale mining Borax is replacing mercury as the preferred method of extracting gold in small-scale mining facilities. The method is called the borax method and is used in the Philippines.
