An analytical system can operate on an analyte, which can be combined with various reagents before being introduced into a flow cell. The apparatus may include a volume into which the reagent to be combined with the analyte is individually drawn. The volume may be formed as a serpentine channel in the valve manifold associated with the pipette used to aspirate the reagent. The reagent can then be mixed by circulating the pump to move the reagent within the mixing volume or channel. To this end, the reagent can be drawn from the receiver into the volume or channel, injected back into the receiver, and this process can be repeated to enhance mixing. |
