Agilent Technologies has introduced the Cary 3500 UV/vis spectrophotometer. The Cary 3500 UV-Vis is designed as clip-together spectrophotometer engine and modules. The engine is common to each configuration and can be paired with one of five different modules to create a customised instrument. It contains a long-life, fast xenon flashlamp as well as the optics that make the high-resolution and high-absorbance measurements possible. Configurations include the Cary 3500 Multicell UV-Vis for measuring up to seven samples and a reference (or other combinations in the eight cell positions). The Multicell spectrophotometer is available in an ambient, temperature-controlled, or multizone configuration. The Cary 3500 Compact UV-Vis is designed for measuring a single sample and reference, and is available in either an ambient or a temperature-controlled configuration.
