no blind alley with this colorimeter The Coleman Electric Colorimeter is different. Other colorimeters, while sometimes adequate for their original purpose, lead only to a dead end when it comes time to upgrade laboratory capability to the more advanced techniques of spectrophotometry. N o t so with t h e Coleman Colorimeter. It provides an easy economical means for growth into spectrophotometry. It uses exactly the same cuvettes, a d a p t e r s , accessories — even t h e same power supply — as the famous Coleman Junior Spectrophotometer. Techniques of operation are almost identical . . . your laboratory technicians can make an immediate transition from colorimetry to spectrophotometry with the Junior. Finally, when the major analytical workload is transferred to the Junior, the Coleman Colorimeter remains a valuable standby instrument. Avoid planned obsolescence in your instrumentation planning . . . equip your laboratory for future growth. Write for Coleman Colorimeter Bulletin AB-259 and Junior Spectrophotometer Bulletin AB-240B.
