FIELD: measuring equipment engineering.
SUBSTANCE: device for taking samples by means of dropper with its washing includes at least two pumping blocks of different volume, rods of which are driven to reciprocal movement by means of common mechanized drive. Working chamber of each of these pumping blocks is connected to contour, containing serially positioned channel, opening into vessel, containing a resource of washing liquid RL, two serially positioned electromagnetic valves EV1, EV2 and pipe TS connected to means for taking samples by means of dropper AP, while working chamber of greater size is connected to portion of contour, providing connection between two electromagnetic valves EV1, EV2 while another working chamber is connected to portion of contour, positioned between second electromagnetic valve EV2 and means for taking samples by means of dropper.
EFFECT: simplified construction.
