Now there’s one spectrophotometer that outperforms them all. It’s the McPherson Model RS 10... the new recording double beam spectrophotometer designed to let you see 30 times more detail in recording analyses of gas, liquid or solid samples. Its wide dynamic range provides uninterrupted scans for measurement from below 2000Á to over 8000Á at absorbances 0-1,0-2 and 0-3 with constant resolution. You can also do emission studies without instrument modifications. Compare the graphs. Notice how much more detail the RS 10 trace shows when stacked against the best in the current state of the art. The RS 10 is actually 30 times more informative and infinitely more useful than any other commercially available spectrophotometer. Our engineers are eager to show you how easily the new RS 10 spectrophotometer can improve your laboratory experiments. Ask for our RS 10 brochure. A call today could help you observe more about the matter of the universe tomorrow.
