Luminometer or fluorometer with an injection device

摘要

The luminometer or fluorometer has an optical axis (O) staying perpendicular on a measuring sample (M). A photomultiplier (10) lies in the axis either directly or via an optical deflection unit e.g. mirror. An injection device includes an injection channel with a section (24b), which is bent relative to another section (24a) of the channel in a direction of the sample. The former section includes an outlet port pointing in the direction. The latter section extends perpendicular to the axis. A lower edge of a lining (16) pointing away from the photomultiplier defines a plane.
