<p>The invention relates to a microfluidic structure for positioning a fluid volume having a plurality of fluid lines (10, 12, 14), of which the fluid volume is to be positioned in a first fluid line (10), and a valve (20). The first fluid line (10) has a first and a second end (16, 18), at which ends the first fluid line (10) is connected to said valve (20). The invention further relates to a method for positioning a fluid volume in a microfluidic system having a plurality of fluid lines (110, 132) and having a valve (122), wherein the first fluid line (110) comprises a first and a second end (118, 120), at which ends the first fluid line (110) is connected to said valve (122). The method comprises the following steps: connecting a second fluid line via a second passage in the valve to the first fluid line (110), filling the first fluid line (110) with a fluid volume, short-circuiting the first fluid line (110) by connecting the first and the second end (118, 120) via a first passage in the valve (122) or blocking the first fluid line (110) by closing the first and the second end (118, 120) by means of the valve (122).</p> |
