You want the utmost accuracy, of course, from instru ment setup to final results. That's why Beckman chart papers should be your unquestioned choice. Because they insure the best possible readings. Our high-quality coated papers are precision-formatted for Beckman instruments. But they give just as excellent results with other makes of instruments also. If our 70 formats don't quite fill your bill, we can custom-design and even imprint chart papers with your institution or company insignia. Then, for ultimate econ omy and convenience, we'll negotiate very worthwhile contract prices — regularly supplying you with any of our papers. Finally, for the ultimate in charting results, we recom mend our excellent assortment of pens. Especially the disposable ones, fiber-tipped in standard and fine-line versions. Users of Beckman instruments know we've built the same high quality into our chart papers that we build into our instruments. And that's the kind of quality your laboratory deserves. So that your instruments can put Beckman® out their best. Get full information by contacting your local Beckman S T RFile U M1328, E N T SScientific , I N C .
