A piezo shaker for shaking a probe comprises a platform 30 operatively connected with at least one piezo element 20a, 20b for moving the platform. Ideally, the shaker may comprise two piezo elements which are arranged to operate along different directions. In use, the probe is placed in a sample container with is placed on the platform, ideally in a rack 40. Each piezo element is connected via a transmission means 50a, 50b to the platform and the shaker further comprises at least one spring bar 60 connected to the platform and a base 70. The shaker may further comprise a power source electrically connected to the piezo elements and controller. Ideally, the shaker comprises a sensor, which may measure the voltage output of the piezo element, to sense the position of the piezo element. |
