For example, the Model 55 has a higher signal-to-noise ratio than you'll find in any comparably priced instru ment. Very important, as you know, when you're working with low concentrations. It allows greater scale expan sions, increasing system sensitivity. Bandpass is a constant 2 nm, eliminating photometric bandpass error in virtually all procedures you run. And photometric error due to stray light is minimal —less than in any other single-monochromator instrument, no matter how much you pay for it. Absorbance to 3A. Drift is less than 0.005A per 8 hours, which means you can relax about the accuracy of your long-term studies. And finally, you'll appreciate the moderate price. But the best way for you to get the complete story is to mail the coupon. Why not do it now?
