Abstract: An analytical device for analysis of chemical or biological samples, a method of using such a device, based on rotation of the device, integrated sample dosing and optical detection, and a system comprising such a device are disclosed. The analytical device comprises a device body having a liquid processing unit. The liquid processing unit comprises a mixing chamber for mixing a sample with a reagent, a sample dosing chamber for delivering a defined volume of the sample to the mixing chamber, and a reagent channel for delivering the reagent to be mixed with the sample, wherein the mixing chamber also serves as a detection chamber.
