Specifications
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. Accessories include special cell
holders, peristaltic pumps, autosampler, a multicell transport, a Peltier
temperature control accessory, and valve unit and valve-pump controller.
The spectrophotometer can be either controlled from HP and non-HP
personal computers equipped with Agilent ChemStation software for
UV-visible spectroscopy (personal computers used should be certified by
UL1950), or from the dedicated handheld controller that comes with the
Agilent 8453E UV-vis spectroscopy system.
