The MicroLab/Avantes Spectrophotometer, Model 211C is a 2048 channel diode array spectrophotometer for measurement of atomic and fluorescence emission spectra.  Long integration times allow detection of weakly fluorescent or dilute samples.  The 211C has very narrow (25 micron) slits and spreads a 740nm spectrum over 2048 detector channels for higher resolution than conventionally seen for educational spectrometers (3-4 times that of diode array spectrometers).  Students are able to easily and accurately resolve closely spaced spectral lines with widely different intensities.

This is a special order item.
