analysis:
Cary Spectrophotometers Record Spectra Around the Clock...unattended ...with the Program Control Accessory This useful accessory enables CARY SPECTROPHOTOMETERS to automatically repeat spectral scans at predetermined time intervals. Scans may be repeated at intervals ranging from as little as 10 minutes to 24 hours, and may be spaced in any desired program. Some laboratories almost double the usefulness of their CARY SPECTROPHOTOMETERS by using them during the day on routine work, then setting them up with the Program Control for automatic analysis during the night. However, automatic programming is just one feature which demonstrates the unmatched versatility of CARY SPECTRO PHOTOMETERS. The wide wavelength range, high resolution, low stray light, plus the availability of a number of useful accessories for other measurement techniques, enable Cary Instruments to serve a wide analytical field. Complete information on these versatile instruments is yours for the asking. Write for Data File A13-79.
