Where can you buy pure borax for science experiments?

As of 2015, lab-grade Borax is available for sale at the website for Science Company. In addition, 99.5 percent pure Borax powder can be bought from many retail stores under the brand name 20 Mule Team.

Borax is widely used both in the lab and in the household. For lab-grade Borax of extremely high purity, consumers can order online from Science Company. Very pure Borax is also sold at K-Mart, Walmart, Target, Shoprite and other retail outlets as a natural household cleaner.

Whether using lab-grade Borax or commercial-grade, apply caution, as Borax can irritate the mucus membranes and cause vomiting and diarrhea if ingested. Borax should be carefully stored away from small children and pets.
