A disposable lid (10) is provided to hermetically seal said laboratory test container (20). A stirrin g element (11) is provided in the disposable lid (10) for processing the material (37) that is introduced into the laboratory test container (20). Sa id stirring element is fitted with a cutting element (29) that rotates about th e longitudinal axis of the laboratory test container (20), said cutting elemen t processing the material (37) together with additional cutting edges (28). Complete homogenization of tissue fragments can be securely achieved by hermetically closing the laboratory test container. |
