FLUOstar Omega

Filter-based multi-mode microplate reader

The FLUOstar® Omega is a multi-mode microplate reader with six detection modes. It utilizes an ultra-fast UV/vis spectrometer or filters for absorbance as well as highly sensitive filters for all other detection modes. The FLUOstar Omega is the ideal plate reader for life science applications.
