For measuring absorbance assays in the visible and UV range, fluorescence and chemiluminescence assays, DNA- and protein concentration with absorbance or fluorescent dyes, cell based assays, cell viability and apoptosis assays. Black Eppendorf Microplates offer an good signal-to-noise ratio. White Eppendorf Microplates are optimized for highest sensitivity in the detection of luminescence signals by maximizing reflection.
