ABSTRACT:
A pipetter capable of mixing liquids and dispensing the mixed liquid has a pipetting tube, an actuating device connected to the tube for sucking liquid into and discharging liquid from the tube, and a flow disturbance device in the tube spaced from the discharge and suction end thereof and adapted to cause longitudinal mixing of liquid in the tube when liquid is moved along the tube in at least one direction. Mixing is effected in the tube by causing a liquid body to move repeatedly to and fro along the tube so that during each such movement at least a portion of the liquid body passes the flow disturbance device and the liquid body is not discharged from the first end of the tube. The pipetter is useful for example in mixing a suspension of blood cells with a reagent prior to analysis.
