Biochrom has introduced two new visible spectrophotometers to their WPA range: the WPA S800+ and S1200+. They are compact, lightweight and include a large display that is easy to read and a simple user interface for rapid setup and analysis. The WPA S800+ is an entry level instrument that performs single wavelength measurements of absorbance, % transmission, concentration and has the ability to perform simple kinetics. The WPA S1200+ adds multi-wavelength measurements and life science methods that include BCA, Bradford, Biuret and Lowry. Both instruments accept standard 100-mm pathlength glass or disposable cuvettes. Optional test tube cell holder and heated cell holder are available.
