Automatic microfluidic device for sample preparation

The microfluidic device (100, 200) has a first reservoir (102, 202), preferably comprising a first liquid (108, 208). The first liquid (108, 208) is held by a capillary shut-off valve (228, 230) in the first reservoir (102, 202). The second reservoir (104, 204) is in fluid communication with the fir...

Zusammenfassung:	The microfluidic device (100, 200) has a first reservoir (102, 202), preferably comprising a first liquid (108, 208). The first liquid (108, 208) is held by a capillary shut-off valve (228, 230) in the first reservoir (102, 202). The second reservoir (104, 204) is in fluid communication with the first reservoir (102, 202). A second reservoir (104, 204) has a second liquid (110, 210) and a sample holder (116, 216) disposed therein. The second reservoir (104, 204) has an inlet opening (145, 236) defined therein. The drainage unit (106, 206) is adjacent to the second reservoir (104, 204). The drainage unit (106, 206) is in fluid communication with the second reservoir (104, 204). The drainage unit (106, 206) has a first absorbent member (158, 218, 858) disposed therein. 微流控装置(100、200)具有优选包括第一液体(108、208)的第一储存器(102、202)。第一液体(108、208)由第一储存器(102、202)中的毛细管截止阀(228、230)保持。第二储存器(104、204)与第一储存器(102、202)流体连通。第二储存器(104、204)具有第二液体(110、210)和设置在其中的样品支架(116、216)。第二储存器(104、204)具有限定在其中的入口开口(145、236)。引流单元(106、206)邻近第二储存器(104、204)
