ABSTRACT:
A device for fluorescence correlation spectroscopy, especially for multicolor fluorescence correlation spectroscopy, in which light rays are focused in a transparent medium located in a sample vessel. Such device includes a vessel holder in which at least two sample vessels with a focussing reflecting bottom are provided, and a common cover for both sample vessels which is at least partly light-transmitting. In a preferred embodiment, a plunger with a light window facing the bottom is inserted into the sample vessel, and the quantity of transparent medium is selected so that the light window of the plunger is immersed in or wetted by the medium.
