Here's a really fast—and easy—^way to make accurate colorimetric tests for pH, chlorine, phosphates, ni trates, etc. Lightweight, portable Taylor Comparators give you de pendable, on-the-spot operational data in minutes . . . not hours! Help you control crystallization, bleaching, precipitation, extraction or waste treatment faster. Tests are made simply by placing the treated sample in the middle tube and mov ing the color standard slide across until the sample matchea one of the standards. Values are then read di rectly from the slide.
Higher purity, increased solution clarity, and greater product uni formity characterize improved ver sion of flocculant now known as Serapan N P 10. Dept. IEC, Dow Chemical Co., Midland, Mich. 27
Many Taylor Comparators serve for several determinations with only a change of color standard slides.
Liquid Epoxy Resins Systems Modifier
All Taylor liquid color standards carry an unlimited guarantee against fading. Be sure to use only Taylor reagents and accessories with Tay lor Comparators to assure accurate results.
Mod-Epox, an organophosphorus modifier, is reported to impart a low initial viscosity, accelerate the rate of cure, and maintain or improve the physical and electrical proper ties of the finished resins. Dept. IEC, Monsanto Chemical Co., St. Louis 4, Mo. 28
