UV-Vis Spectrophotometers
Family Brief
UV-vis spectrophotometry is common but power analytical technique used to measure UV and visible light intensity passing through a sample solution. The LabTech Bluestar series UV-Vis spectrophotometers have consistent, high-quality performance with a powerful PC controlling software to support various applications from biotesting to water quality testing.
-
The Bluestar A is a high-performance, easy-to-use instrument with a fixed bandwidth of 2nm.
-
The Bluestar B is a high-performance, easy-to-use instrument with 1nm and 2nm bandwidth options.
