  • Publication number: 20140245842
    Abstract: The invention provides a method for detaching and/or isolating a histological sample that is adhering to another sample and/or to the inside of a cassette, for example as a result of solidification of an embedding medium within a cassette. The sample is immobilized in a sample receiving chamber above a first fill level of a liquid that is suitable for counteracting the adhesion; and that the fill level of the liquid is then elevated at least until said level reaches the sample. An apparatus according to the present invention that can be used for carrying out the method comprises a sample receiving chamber and an adjusting chamber, the adjusting chamber being connected to the sample receiving chamber in such a way that a change in the fill level height of the liquid in the sample receiving chamber is producible by changing the pressure existing in the adjusting chamber.
