Patent
CA 2647831
The invention relates to a reagent cartridge (2), which can be exchangeably inserted into an analyzer (1) and comprises a plurality of reagent bags (A, B, C, D), said reagent bags (A,B,C,D) being furnished with connecting lines (6, 7, 8, 9), each of which may optionally be connected to an input device (3) of the analyzer. According to the invention each reagent bag (A, B, C, D) has an analyzer-controlled multi-way valve (10, 10') with at least two valve positions at the point where the respective connecting line (6, 7, 8, 9) departs, such that the first valve position opens a fluid path between the connecting line (6,7,8,9) and the reagent bag (A, B, C, D), while the second valve position closes off the reagent bag (A, B, C, D) and opens a fluid path (11) between a ventilation source, preferably ambient air, and the connecting line (6, 7, 8, 9). The connecting lines (6, 7, 8, 9) of the reagent bags (A, B, C, D) departing from the multi-way valve (10) open directly into a common rail (12) or a collector valve (27).
