Method and device for preparing samples

摘要

The method involves fixing a carrier to a holder that is located in an environmental chamber, and applying a sample liquid on the carrier for wetting the surface of the carrier with sample liquid. Change in optical properties of an absorbing medium resulting from the absorption of excess sample liquid into the absorbing medium is detected by an optical sensor device. A blotting device (5) is moved-away from the carrier due to the change in the optical properties of the absorbing medium detected by the sensor device. The absorbing medium is illuminated by a light source (9). An independent claim is also included for a device for preparing specimens for an electron microscope.
