This is a used Agilent 8453 UV-Visible Spectrophotometer. Tested working.
The Agilent 8453 spectrophotometer is a single-beam, microprocessor-controlled, UV-visible spectrophotometer with collimating optics. With its diode-array technology, the spectrophotometer is much faster than comparable conventional instruments—with more precision, more sensitivity and more reproducible results.
