Abstract
Abstract A sample distributor for a liquid substance being examined has containers for all samples and for individual sample portions along with a part inseparably connected therewith for receiving sample information. The distributor also includes a supply unit for total sample containers, a reader for reading the information of total sample containers, a store tank receiving the individual sample containers, a supply unit for forwarding the individual sample containers to a sample dosing device and an information transmitting device. The sample dosing device receives a predetermined amount of liquid corresponding to the actual investigation program from the total sample container and transmits it to the individual sample containers, while the information transmitting device transmits information received by the reader to the individual sample containers. There are also provided means receiving the filled individual sample containers provided with information, as well as a device steering and supervising the entire operation of the sample divider.
