| 摘要 |
The invention relates to an apparatus for transporting a fluid in a channel leg of a microfluidic element, especially of a flow cell. According to the invention, a pressure source for pressurizing a front end face (42) in transport direction of the liquid which completely fills the channel leg in cross section is provided. The pressure source preferably comprises a closed space (17; 22; 34; 36, 38, 40), in which a compressed gas, for example air, is compressible by moving the front end face (42) of the fluid transported in the channel leg. |
