A method and instrumentation for the micro dispensation of droplets

It is a method for distributing liquid waterdrop to the microsystem of the form of the disk which includes a target region (TA) in the surface. The disk in which i (A) target region has separated the method, and a trigger mark exists, (B) Spina where it is a step which offers dispenser composition, and this dispenser composition turns a disk to the circumference of a axis, b) With d distributing signal with the waterdrop dispenser which can distribute waterdrop to TA, and the trigger position to which c disk exterior was fixed. The step containing the controller which can carry out the trigger of the distribution of the waterdrop to the inside of TA as a function of the trigger mark which passes a trigger position, ii) A disk is arranged in Spina and it is characterized by including the step which programs for a controller the value for the distribution parameter which gives distribution of waterdrop to TA, and the step which distributes waterdrop while an iii disk carries out a spin. A disk includes two or more discrete target regions. Target regions may be a part of one or more micro channel structures, and may function as an entrance port of a liquid. The present invention includes dispenser composition similarly.
