UV-Visible Spectrophotometer | U-5100 Ratio-Beam


Eco-friendly and high-performance, the U-5100 is the best choice for a wide range of applications from teaching and routine QC to biotech and environmental testing.

This entry-level instrument utilizes ratio beam optics to give exceptional stability for a host of applications including kinetics, and offers full scanning capabilities. Routine analyses are readily carried out using the simple-to-use photometry, absorbance ratio, and time scan modes. The U-5100 also features an eco-friendly design using an ultra long-life pulsed Xe lamp and easy operation with a large LCD and standard automatic 6-cell changer.
