Abstract
The application relates to a device for measuring the optical density of samples arranged in strips on a plate. The device comprises a measurement head (3) moving strip by strip in relation to the plate, said measurement head (3) including a light source (4) and a detector (5). Outside the strips, there is provided a transparent spot (9) or a light-proof spot (10), at which the light source intensity or the background signal can be measured either before or after the strip measurement. By employing the single-channel device according to the invention, it is possible to achieve virtually the same speed level as with a multichannel device. However, the device of the invention can be made remarkably simpler. One single-channel device can also be used for measuring several different plates.
