Laboratory pumps

Laboratory pumps are fluid-handling devices that move, meter, or evacuate liquids and gases under controlled conditions in research and process settings. They cover a wide span of mechanisms, from peristaltic heads that drive fluid through flexible tubing to vacuum pumps that evacuate chambers and syringe units that deliver microlitre volumes at a set rate. On Questpair, 86 percent of the 2216 listings are used, the remainder new, offered by 24 verified suppliers and distributors across 11 countries. New, used and refurbished units appear in the catalogue, with prices spanning EUR 1 to EUR 1.549.601. The choice between them turns on flow range, chemical compatibility, and whether the application needs contamination-free paths or precise dosing.
