The
Free Year.
Yours from Corning with our 2-year guarantee on pH meters. Not just one year. Two. So you get a free year. If anything goes wrong with a Corning pH instrument within 24 months of delivery to you, and it's our fault, we'll take care of it. All you must do is return the guarantee-registration card when you buy the instrument, and have it serviced only by Corning or authorized
Corning Scientific Instrument dealers. We've put the longest guarantee on the longest line. Choose from 12 pH instruments. Analog or digital. Portable to expanded-scale research. The free year is yours from the same people who guarantee pH and reference electrodes for six months. In writing. Call your dealer for a demonstration. Or contact us. Corning Glass Works, Scientific Instruments, Medfield, Mass. 02052.
