BRIDGES THE GAP • EXCELLENT RESOLUTION UV-VISIBLE RANGE · MODERATE COST Until now, the analytical and clinical chemist faced a gap in spectrophotometric instrumentation: Either choose an intermediate instrument priced under $1,700 or a high resolution instrument priced near $3,500. This wide cost differential forced many analysts to accept less in range and resolution than they desired. Now the Perkin-Elmer UV-VIS Spectrophotometer, Coleman Model 111, bridges this gap. This new instrument provides the resolution of a 2 ιτιμ band pass, dual light source, wavelength range of 200-900 π\μ, plus proven dependability—and it's priced at $2,200 (only $1,750 for the 340-900 m μ model). • Spectral band pass of 2 mM is constant throughout the wavelength range—wavelength accuracy is better than 0.5 πΐμ. • Exclusive, dual-range phototube detector covers the entire 200 to 900 mM range—eliminates mid-operation switching and prevents positioning errors. · Dual light source, selected by operating a lever, provides a tungsten lamp for visible and a deuterium lamp for ultraviolet work. · Large sample compartment accommodates cells up to 100 mm.
