β Real versati l i ty—9 cuvette sizes and types —sample volumes from 10 ml to .007 ml . The entire range of cuvettes, adapters, and accessories for the world-famous Junior Spectrophotometer can be used directly with the Model 8 Colorimeter! No other filter instrument has this complete flexibility, this tremendous choice of sample volume.
# 4 ways to measure wi th dual measuring system. Both Optical Density and % Transmittance readings by either of two methods —instant, direct-reflection readings from the illuminated galvanometer scale, for speed and convenience; null-point readings from the calibrated slide-wire potentiometer, for the highest possible precision. No other co/orimeter offers this combination of precision and convenience.
# You can read concentrations directly wi th removable scale panels. Interchangeable panels can be calibrated to read concentrations directly . . . A tremendous time-saver! Plus . . . The same fine photocell and taut suspension galvanometer combination, the same rugged construction, the same selection of power supplies employed by the famous Coleman Junior Spectrophotometer.
