Beschreibung
Zusammenfassung:	A method for dispensing droplets of a liquid to a microsystem in the form of a disc comprising a target area (TA I) in its surface, said disc preferably being a microfluidic disc comprising a microchannel structure with an inlet port that is a target area (TA I). The method is characterized by comprising the steps of:i) providing (1) said disc which has a triggering mark, and (2) a dispenser arrangement comprising:a) a spinner for rotating the disc around its axis,b) a drop dispenser permitting dispensation of droplets to inlet port I,c) a fixed trigger position outside the disc, andd) a controller which is capable of triggering the dispensation of a droplet into (TA I) as a function of the triggering mark passing the trigger position,ii) placing the disc in the spinner and programming the controller with values for dispensing parameters that will give dispensation of the droplets to TA I,iii) dispensing the droplets.The invention also comprises the dispenser arrangement as such.
