The invention relates to a particle injector for introducing particles into a carrier flow of a microfluidic system, especially for injecting biological cells into the carrier flow of a cell sorter. The particle injector includes an inlet for receiving the carrier flow, an outlet for discharging the carrier flow including the introduced particles, a carrier flow channel which connects the inlet to the outlet, and an injection channel flowing into the carrier flow channel for introducing the particles into the carrier flow. The inventive particle injector is characterized in that the carrier flow channel has substantially no dead volume.

Particle injector for a cell sorter

A coupling device (), particularly for liquid-tight coupling of at least one liquid line () to a fluidic system (), is described, which comprises: at least one sealing device (), which is implemented to receive an end region () of the liquid line () and has a first sealing surface () for placement on an external surface () of the fluidic system in such a way that the end of the liquid line () is laterally enclosed by the first sealing surface () and points toward an opening () in the external surface (), and a clamping device (), using which the sealing device () may be pressed against the fluidic system (), so that the first sealing surface () produces a liquid-tight connection with the external surface ().
