Applications
The Coleman 139 spectrophotometer was used in laboratory and analytical settings for quantitative chemical analysis, including pharmaceutical testing, clinical diagnostics, and material analysis. Capable of measuring light absorption across UV and visible wavelengths for concentration determination and spectral characterization. Typically interfaced with recording and data acquisition systems via its recorder and digital outputs.
This Hitachi Perkin-Elmer Coleman 139 UV-VIS Spectrophotometer (P/N 139-0171) is being sold AS-IS for parts or repair. We are not able to confirm functionality due to the unit's age, and no operational testing has been performed. The instrument is cosmetically fair to good for its age — the white housing shows general aging, surface scuffs, and some discoloration, but the analog meter face, front panel controls, and knobs appear intact. The light source compartment is accessible and both lamps are present. A loose internal subassembly (small circuit board with DIP switch block and wiring harness) is included and visible in the photos, though its relationship to the instrument is unclear. The detached multi-pin cable is also included. Please review all photos carefully before purchasing. This unit is not guaranteed functional and is sold strictly as-is. Please view our photo set and contact us if you have any questions.
