Perkin-Elmer UV/Visible spectrophotometer Lambda 10 Perkin-Elmer UV/Visible spectrophotometer Lambda 10
Lambda 10 UV/Vis spectrophotometer is a general purpose instrument for absorption spectroscopy in the ultraviolet and visible spectral regions. Besides the standard scanning spectra mode, the supporting software has capabilities to perform kinetic measurements as well as certain automatic data conversions(to concentration units, for example).
