Optical detectors

Optical detectors are instruments that measure light, either the amount a sample absorbs across a wavelength range or the signal it emits, and convert that reading into a quantitative result. On Questpair, 1428 optical detector listings are available from 21 verified suppliers and distributors across 11 countries. Of those, 97 percent are used and the remainder new, so the catalogue leans heavily toward second-hand units. New, used and refurbished laboratory detectors appear side by side, with prices from EUR 17 to EUR 215.222. The category covers UV-Vis spectrophotometers, benchtop and analytical models, and HPLC detectors, the devices that underpin routine absorbance measurement in most laboratories.
