Patent ID: 11680929

Abstract:
An apparatus for collecting liquid fractions from a separation/reaction apparatus (1). A capillary (2) guides an extracted liquid fraction to a branching unit (3), a collection arrangement (4) carries a plurality of target vessels (5) receiving the liquid fraction from the capillary and a fluid line (6) is flow-connected to a fluid pump (7) and opens into the branching unit. The capillary and the fluid line each have outlet openings in the direct vicinity of one another at their end facing a target vessel such that liquid emerging from the outlet opening (2′) of the capillary transitions into the outlet opening (6′) of the fluid line. This precludes back mixing with earlier/later liquid fractions, precludes uncontrolled dripping of sample substance at the transfer point, speeds displacement of the target vessels in the collection arrangement, facilitates automation of the fraction processing procedure, and results in a more compact fraction collection apparatus.
