High voltage power supplies

High voltage power supplies are instruments that deliver regulated electrical output, from a few volts to several kilovolts, to drive laboratory equipment and experiments. The Questpair catalogue holds 390 of them from 14 verified suppliers and distributors across 10 countries, listed new, used and refurbished. Of those, 96 percent are used. Prices run from EUR 1 to EUR 55.958, a span that reflects how far the term reaches: a small bench unit for teaching sits at one end, a sealed kilovolt source for electrophoresis or detector bias at the other. A laboratory buyer choosing among them starts not from the brand but from the voltage, current and regulation the application actually needs.
