Baths / circulators

Baths and circulators are temperature-controlled laboratory instruments that hold a liquid at a set point and, in the case of a circulator, pump it through an external loop to regulate a connected apparatus. A simple water bath heats and holds; a circulator adds flow, driving fluid to a reaction vessel, a jacketed cell or a condenser. Across the Questpair catalogue, 1285 units are listed as new, used and refurbished laboratory equipment from 17 verified suppliers and distributors. Of those, 89 percent are used and the remainder new. Prices run from EUR 38 to EUR 7.998. The spread covers small benchtop baths through to high-capacity recirculating chillers built for continuous duty.
