Absorbance

The Thermo Scientific Multiskan SkyHigh is a monochromator-based UV-Vis microplate spectrophotometer (200–1000 nm) compatible with 6- to 384-well plates. The Multiskan FC is a filter-based microplate photometer (340–850 nm) and an established/proven model for ELISA and routine work — its age alone shouldn't rule it out.
