Abstract (en)
[origin: WO2017084766A1] A cover (10) for use in a digital microfluidics system (16) for manipulating samples in liquid portions or droplets is provided. The digital microfluidics system (16) com- prises a first substrate (18) with an array of electrodes (24) and a central control unit (20) for controlling the selection and for providing a number of said electrodes with voltage for manipulating liquid portions or droplets by electrowetting. A working gap (30) with a gap height is located parallel to the array of electrodes (24) and in-between first and second hydrophobic surfaces (26,28) that face each other at least during operation of the digital microfluidics system (16). The cover (10) comprises on one side the second hydrophobic surface (28) and on another side at least one micro-container interface (32), which comprises at least one cone (34). The inner surface of the cone (34) is formed to provide a sealing form fit contact with an outer surface of an inserted micro-container nozzle (36), by which a liquid is transferrable through a fluidic access hole (38) formed into the cover (10) and interconnecting each cone (34) and the gap (30). The cover (10) may be part of a disposable cartridge (14) or may be provided separately.
