HPLC pumps

HPLC pumps are the fluid-delivery component of a high-performance liquid chromatography system, driving solvent through the column at the controlled, high-pressure flow that separation depends on. Across the Questpair catalogue, 1146 HPLC pumps and related modules are listed from 14 verified suppliers and distributors in 14 countries. The marketplace carries new, used and refurbished laboratory units, and 99 percent of the listings are used. Prices run from EUR 1 to EUR 107.611, a span that covers bare pump heads at one end and complete chromatography systems at the other. A pump is rated by its flow range, its pressure ceiling, and whether it mixes solvents on the low or high pressure side of the column.
