Peristaltic pumps

Peristaltic pumps are positive-displacement fluid transfer devices that move liquid by compressing and releasing a length of flexible tubing with a rotating set of rollers, so the pumped medium touches only the tube and never the mechanism. That isolation is why they dominate sterile and contamination-sensitive work in laboratory and bioprocessing settings. Across the Questpair catalogue 991 peristaltic pumps are listed from 18 verified suppliers and distributors in 9 countries. New, used and refurbished units appear side by side, and 97 percent of the listings are used, the remainder new. Prices run from EUR 43 to EUR 55.954.
