Microplate readers

Microplate readers are laboratory instruments that measure optical signals from samples held in the wells of a microtiter plate, typically in 96, 384 or 1536-well formats. They quantify absorbance, fluorescence or luminescence across many samples at once, which is what makes them central to assay-based work. The Questpair catalogue lists 751 microplate readers from 20 verified suppliers and distributors across 11 countries, in new, used and refurbished condition. Among those listings, 94 percent are used. Prices run from EUR 1 to EUR 107.611, a span that separates a bare single-mode unit from a fully equipped multi-mode platform.
