摘要： The invention is directed to a device for performing multiple analyses from one sample in parallel with a liquid sample. It is proposed that the device comprises reaction sections (7) connected to a venting system comprising venting channels (8), wherein the capillary force of the reaction sections (7) to the sample is greater than the capillary force of the venting system and the venting system is designed for venting several reaction sections (7) in common.

摘要： The present invention is related to a microfluidic device capable of conveying a liquid (19) by capillary forces. Said microfluidic device comprises a microfluidic channel system (10, 12, 14; 43, 44; 63, 64) with

i) one liquid supply compartment (81, 91, 101) and ii) a first channel (10) connected to the liquid supply compartment (81, 91, 101), having at least one non-closing valve (1, 65, 73) located downstream of the liquid supply compartment (81, 91, 101) and
ii) a second channel (12, 43, 44). The second channel (12, 43, 44) branches-off from the first channel (10) downstream of the liquid supply compartment (81, 91, 101) but upstream of the at least one non-closing valve (1, 65, 73) and which re-united with the first channel (10) at the location of the non-closing valve (1, 65, 73) to form an outlet channel (14). The second channel (12, 43, 44) does not contain any non-closing or closing valve thus creating an unobstructed liquid flow path connecting the liquid supply compartment (81, 91, 101) with the outlet channel (14).
