Abstract: A device for spinning a liquid sample on a sample carrier (2), such as a microscope slide, comprises a rotatable body (4) with a receiving surface (11) for the sample carrier (2), and a chamber (10) for enclosing a sample that has been applied to the sample carrier (2). A means (23) is designed to establish a gas flow from the environment into the chamber (10) in connection with the spinning of the sample in order to prevent leakage of the sample to the environment. Unlike current designs, the chamber (10) is arranged on the same side of the sample carrier (2) as the rotatable body (4). Consequently, the sample carrier (2) itself serves as a cover which seals the chamber (10).
