Fraction collectors

Fraction collectors are laboratory instruments that divide the continuous output of a chromatography column into separate timed or volume based portions, directing each into its own tube or well so that peaks eluting at different times are captured apart. They sit downstream of HPLC, FPLC and preparative separation systems, where recovering a purified compound depends on collecting the right eluate at the right moment. Across the Questpair catalogue, 141 fraction collectors are listed, both new and used, from 10 verified suppliers and distributors in 6 countries. Of these, 96 percent of the listings are used. The field they serve, preparative and analytical chromatography, is what shapes how any one model is chosen.
