This IR spectrum came from a $3,000 instrument

The new Model 700. It's from Perkin-Elmer—and did you ever see such performance from an instrument costing $3,000?

Here's the perfect IR training or research tool for the academic lab, and for industr ial plants where many reliable spectrophotometers are needed for analytical and qual­ity control work.

Its performance is what you'd expect from a quality instrument. That's because—even with its low cost—the Model 700 offers a grating monochromator forgood resolu-tion.the convenience of push-button operat ion, and clean, unbroken chart presentation, linear in fre­

quency with a scale change at 2000cm\

The Model 700 op­erates from 4000 to 650 cm·1 (2.5-15.4/*) —the most inform­at ive area of the s p e c t r u m . It has many features that we'd like to tell you more abou t .
