FINGERPRINT ORGANICS AT THE B E N C H wi th t h e Beckman IR-5 Double-Beam

Infrared Spectrophotometer

Backed by thousands of IR reference spectra, Beckman's low-cost IR-5 Double-Beam Spectrophotometer brings the benefits of infrared analysis right to the bench of every chemical laboratory.

And -with these benefits, the IR-5 brings features previously found only in more expensive infrared spectrophotometers: a flat-bed recorder that produces a 2-16 micron spectrum on a full-size chart; a hermetically-sealed monocriromator for protection against dust, moisture, and corrosive fumes; and capabilities as either a double-beam or single-beam instrument.

With simple, push-button operation; wide range of sampling accessories; and high resolution and reproducibility; the Beckman double-beam IR-5 and single-beam IR-6 are making qualitative and quantitative I R analysis a practical tool for the chemist, and a simple solution for the spectroseopist's routine work. Contact your nearest Beckman regional office for a demon­stration, or write for Data File 3L-33A-18.

Columbian's colloidal carbon dispersions make highest-quality enamels with only simple mixing

The labor, power and equipment cost of milling can be completely eliminated from the making of black paints, lacquers, enamels and plas­tics. At the same time, the color and finish of the product is actually im­proved! The reason is simple and logical. Few plants can equal Co­lumbian's experience, equipment and techniques for making com­plete, perfect colloidal dispersions of carbon. So perfect are they, that usually less black will give the de­

sired color, a t a saving in cost. Fur­ther, tliese dispersions are dustless. You c a n make black enamels side by sid-e with light colors. Colum­bian's colloidal dispersions are avail­able i n almost every useful media, with a choice of uniform character­istics i n the dispersed colloidal car­bon particles. One is ideally suited to youzr need. Consult us about your application. Or send now, without obligation, for literature on Colum­bian colloidal dispersions.
