Abstract
A disposable cartridge configured as a digital microfluidics system for manipulating samples in liquid portions having a cartridge accommodation site and a central control unit for controlling selection of individual electrodes of an electrode array located at the site and for providing plural electrodes with individual voltage pulses for manipulating liquid portions by electrowetting. The cartridge has a hydrophobic working surface and a rigid cover with a second hydrophobic surface, the hydrophobic surfaces facing each other and being separated in parallel planes by a gap. The cartridge has plural pipetting guides for safe entering/withdrawing liquids into/from the gap with a pipette tip. At least one of the pipetting guides provides an abutting surface sealingly admittable by a counter surface of a pipette tip, located at a pipetting orifice that reaches through the rigid cover, and configured to prevent a pipette tip from touching the hydrophobic working surface.
