Agilent 8453 Diode Spectrophotometers, 190 – 1100 nm, Agilent (CAT#: STEM-SPO-0044-LGZ)

The Agilent 8453 Spectrophotometer is an essential part of the UV-Vis system. Routine and occasional users can take advantage of the features of diode arrays, including fast scanning, excellent sensitivity, and near-absolute wavelength reproducibility.
Featuring exceptional ruggedness and reliability, this Agilent spectrophotometer is easy to use with line power indicators, status indicators and other buttons. The device uses a photodiode array (PDA) for high reliability. Measuring the entire spectrum simultaneously using the array takes less than a second. Use data analysis software for efficient data analysis and archiving, ensuring compliance with Good Laboratory Practice and Pharmacopoeia requirements.
