Device and method for the mixing of substances, in particular of dyes

The device (1), which serves for mixing substances, in particular dyes, has a processor unit (2), one serving for the storage of mixing formulas local storage unit (3), a display unit (4) and an input unit (5), and a measuring device (6), in particular a balance, with the proportions of substances in accordance with a mixing formula specified amounts manually or automatically can be filled into a container (61). The processor unit (2) is further connected with a communication module (7) is created with the wireless communication connection to a data server (30, 300) via the data of mixing formulas to the local storage unit (3) are transferable. Therefore, the method for operating the device (1) allows a user to always current mixing formulas directly to the mixing device (1) retrieve and then to start a mixing process or manually perform a mixture in accordance with the display of the measuring device.
