ABSTRACT:
The invention relates to a device and a method for carrying out simultaneously multiple analyses in a liquid medium. The device comprises a compartment for introducing liquid, communicating through a distribution channel with separate analysis compartments. Each analysis compartment is provided with valve-forming means, such as a ball, isolating the liquid contained in the analysis compartment from the liquid remaining in the distribution channel. The device is particularly suitable for microbiological analyses.
