Ultraviolet systems

Ultraviolet systems are laboratory instruments that generate or apply ultraviolet light for a defined purpose, most often to bond nucleic acids to a membrane, to visualise them in a gel, or to sterilise a surface. The category spans benchtop crosslinkers, transilluminators and hand-held UV lamps, and across the Questpair catalogue 218 of them are listed from 14 verified suppliers and distributors in 10 countries. New, used and refurbished units all appear here. Among the current listings, 99 percent are used. Prices stretch from EUR 1 to EUR 6.500, which separates a replacement bulb from a complete instrument. The dominant brands are UVP, Analytik Jena, Keyence, Stratagene, Spectroline.
