Fisher Scientific provides 152 solvents. And you can rely on the purity of each. Because all Fisher solvents meet, often exceed, specified purity levels. Three examples: Fisher Anhydrous Ethyl Ether is practically free of water and ethanol; yet there's no worry over the buildup of dangerous peroxides. Only 0.000005% of sodium diethyldithiocarbamate* inhibits oxidation. Fisher 1,4Dioxane's freezing point averages +11.7°C—higher than any other available; so low in peroxides and carbonyls no stabilizer is needed. Fisher Chloroform is the lowest in price; yet none other rates higher in purity. Three reasons why if your first thought isn't Fisher solvents, think again. Fisher...first. • U.S. Pat. No. 2,818,438
