Low in initial cost because of its basic design, a Coleman pays for itself in time saved from tedious calibration and operation. Two models are available: the Model 6, Junior Spectrophotometer idéal for routine lab work or testing in the plant . . . and the Model 14, Universal Spectrophotometer for fine analytical work, with long or short path cells and adaptable to fluorescence and haze measurement.
