The utility model relates to a sample injector for a laboratory. The sample injector comprises a sample injector body, the whole sample injector body is of a tubular structure with an open top end and a sealed bottom end, the bottom end of the sample injector body is an inclined surface, and a filling hole is formed in the bottom end of the inclined surface. The sample injector body can slowly add one liquid into another test tube and enable the liquid to flow down along the inner wall of the test tube, so that the upper liquid level and the lower liquid level are clearly layered. The axial cross section of the side wall of the bottom end of the sample injector body is step-shaped, so that liquid can be effectively controlled to slowly flow into the inner wall of the test tube, unclear layering caused by manual operation is effectively reduced, the working efficiency can be improved, and the working fatigue is reduced. In addition, the tail end of the communicating pipe, vertically extending downwards, of the
