Sampler (11) for independent taking of samples from a body cavity, such as cervical samples. Optimum accessibility of the cervix is achieved through the fact that the sampler comprises a rigid plastic tube (14) which is rounded at the front side. As a result, during its introduction by the user, the sampler can accurately be moved to the cervix. Moreover, the sampler is surrounded by the vagina and it is possible to prevent leakage of flushing liquid (15), and consequently it is possible to make do with a relatively small quantity of flushing liquid (15) while at the same time producing a sample with a high concentration of cervical cells. In this way, it is possible to reach the sampling location in a simple and more accurate way which does not damage tissue. As a result of the tube simultaneously being designed as a cylinder for a plunger (12), it is possible, firstly, to flush the desired location with a solution using a cylinder-plunger assembly obtained in this way and, secondly, to take the sample by drawing the plunger (12) back.
