Abstract
A microfluidic processing unit for the automated processing of liquid samples and method thereof are disclosed. In one embodiment, the unit comprises first and second main channels connected to a pump for generating a negative or positive pressure therein; a sample channel which supplies a liquid sample is connectable to a sample vessel containing the liquid sample, the sample channel communicates with the first main channel and is equipped with an on/off valve; one or more reagent channels for supplying one or more reagents, the reagent channels being connectable to reagent vessels containing reagents for reacting with the liquid samples, each of the reagent channels communicating with the first or second main channel and being equipped with an on/off valve; and a reaction chamber for reacting a sample and reagent, the reaction chamber being connected to the first and second main channels via at least one on/off valve.
