There are three models in the 67 series - Model 6700 covers the visible range of the spectrum and has a 4nm bandwidth; Models 6705 and 6715 cover the UV/visible range of the spectrum and have a 4nm and 1.5nm bandwidth respectively. All three instruments have modes for photometrics, spectrum scanning, multi-wavelength analysis, kinetics and quantitation, giving direct concentration results against single or multi-point calibrations. With extensive post measurement tools to ensure results are presented exactly to each users requirements the 67 series spectrophotometers also offer significant advances in data portability.
