Pipetting device and sample analyzer

The utility model discloses a pipetting device and a sample analyzer, the pipetting device comprises a support, a pipetting needle and a baffle plate, the pipetting needle is arranged on the support and is used for liquid transfer; the baffle is arranged on the support and comprises a first side wall, the plane where the first side wall is located intersects with the extending direction of the pipetting needle, a notch is formed in the first side wall, and at least part of the pipetting needle is located in the notch. When the pipetting needle is used for pipetting, bubbles generated at the position of the needle tip of the pipetting needle are broken at the notch, so that bubble residues of the pipetting needle are reduced, and crystallization of the needle tip of the pipetting needle is reduced; and when the pipetting needle discharges liquid, the phenomenon of bubble film formation is not easy to occur at the tube orifice of the test tube, so that liquid hanging of the pipetting needle caused by breakage o
