Abstract

The present disclosure is directed to a dispensing system for providing a preset small volume of liquid ≤200 μl into a filling area of a microfluidic sample carrier comprising at least one flow channel, the system including, inter alia, at least one interface unit provided for each flow channel of the microfluidic sample carrier, with each interface unit comprising an injector with an injection channel, wherein the cross section of an outlet part of the injection channel is larger than a cross section of an inlet part of the injection channel and of the middle part of the injection channel. Furthermore, the present disclosure relates to a respective microfluidic sample carrier sealing system and to a respective method of dispensing sealing liquid into a microfluidic sample carrier.
