The Multiwell-plate reader is an external module that is attached to the FS980 to perform spectral or time resolved measurements on multi-well plates. The multiwell plate reader module is coupled to the FLS980 by means of a bifurcated optical fibre. The control of the module is fully automated from the F980 software, temperature near the well plate is recorded. Spectral range depends on FLS980 spectrometer configuration and bifurcated fibre assembly. 96 well and 384 wells are available.
