Abstract: A method of treating an isolated area of a sample with a liquid is disclosed. The method has the steps of generating an isolated area of a sample by a first fluid reservoir where the first fluid reservoir enclosing a distal end of a second fluid reservoir and the isolated area of the sample being sealed towards the remaining area of the sample, bringing the isolated area of the sample into fluid connection with the second fluid reservoir, dispensing a fluid from the second fluid reservoir into the first fluid reservoir thereby generating a fluid flow on the sample at the isolated area in a first direction, and aspirating the fluid from the first fluid reservoir into the second fluid reservoir thereby generating a fluid flow on the sample at the isolated area in a second direction.

Abstract: A cartridge, in particular a disposable cartridge, for use in an electrowetting sample processing system. The cartridge contains an internal gap with at least one hydrophobic surface for enabling an electrowetting induced movement of a microfluidic droplet that has magnetic beads and further has a bead accumulation zone, into which the microfluidic droplet is transferable by electrowetting force and the magnetic beads are exposable to a magnetic force of a bead manipulation magnet. The internal gap has a bead extraction opening adjacent to the bead accumulation zone. The bead extraction opening provides a passage from the gap to an exterior space of the cartridge and is configured to removably receive the bead manipulation magnet for enabling an extraction of the magnetic beads from the microfluidic droplet by a removal of the bead manipulation magnet.
