Visible Spectrophotometry optimised for the teaching laboratory

The S800 visible spectrophotometer has been designed to meet the needs of both students and technical staff in education. The instrument is small and light in weight with a large display for ease of reading. The S800 measures Absorbance, % Transmission and concentration as well as being able to output absorbance–time plots directly to chart recorder. In addition, the user manual includes simple experiments for the determination of ë max, extinction coefficient and natural bandwidth as well as the construction of a standard curve and the measurement of stray light. Furthermore, the instrument is delivered with Grafico, a PC utility software package, and the requisite serial lead, providing the student with the means to capture, print and interpret a wavelength scan from the instrument on a PC; the data for the scan or other results can be easily exported from Grafico to Excel. Note that Grafico also includes an educational tutorial on UV/Visible spectrophotometry. The S800 accepts standard 10mm pathlength glass or plastic cuvettes; alternatively; a test tube adapter set is available. The cell holder can be removed for cleaning. The instrument is delivered with a starter pack of disposable plastic cuvettes.
