ABSTRACT:
The device (10) for the stepwise transport of liquid, particularly of sample liquid to be analyzed, through several reaction chambers located in series in terms of flow while utilizing capillary forces comprises at least one channel (14) through which liquid is transportable on the basis of capillary forces. Further, the device (10) comprises at least two closed vent holes (38,40,42) which are in fluid communication with the channel (14) at connection sites (22,24,26) spaced from each other along the channel (14). The connection sites (22,24,26) divide the channel (14) into several channel sections (44,46,48). The fluid connections between a respective channel section (44,46,48) and the vent holes (38,40,42) allocated thereto can be opened separately.
