Apparatus (1) for determining a property of a sample. The apparatus has a chamber (11, 13) for receiving at least a part of the sample and contains a rotor (15) adapted to rotate within the chamber (11, 13). The apparatus (1) also has a space (17) between the rotor (15) and the chamber (11, 13) which may be at least partially occupied by the sample, driving means (14) for rotating the rotor (15), and a detector (39) arranged to detect the rate of rotation of the rotor (15). The apparatus may also have two parts, a sample strip (5) for receiving the sample and a receiving member (3) for receiving the sample strip (5) and carrying out measurements on the sample. The rotor (15) may be magnetized across its diameter. The driving means (14) may be a magnetic driving means. The sample may be a blood sample. The property to be determined by the sample may be the prothrombin time of the blood or plasma. |
