Abstract: A tool device for the automated opening of flip tubes including an actuating plunger which is provided and configured to move the actuating portion at least in open direction and thereby to exert an opening moment on the lid portion, and wherein the device further includes a damping means which is configured to exert a damping moment on the container lid at least during a period of the actuation of the actuating portion by the actuating plunger, which damping moment is less in amount and is in an opposite direction compared to the opening moment.

Abstract: A process for hydrophobically coating a pipette tip by wetting at least regions of the inside of the pipette tip with a wetting solution, the process including: providing a holding cavity other than the pipette tip on a pipette device, immersing the holding cavity in the wetting solution, aspirating wetting solution into the holding cavity, connecting the pipette tip to the holding cavity, dispensing the aspirated wetting solution from the holding cavity through the pipette tip so as to rinse a pipetting fluid holding chamber portion inside the pipette tip, and evaporating solvent contained in the wetting solution.

Abstract: Processes for hydrophobically coating a pipette tip by wetting at least regions of the outside and inside of the pipette by with a wetting solution are disclosed. Such a process may include coupling the pipette tip to a fluid pressure source having variable fluid pressure, immersing the coupled pipette tip in the wetting solution, aspirating wetting solution into the pipette tip, dispensing the aspirated wetting solution, and evaporating solvent contained in the wetting solution.

Abstract: The present invention relates to a pipette tip (10), for aspirating and dispensing pipetting fluid, which extends along a pipette tip longitudinal axis (L), a first axial longitudinal end region (16) of the pipette tip (10), as a pipetting longitudinal end region (16), comprising a pipette opening (12), through which pipetting fluid can flow in the course of operation, and a second axial longitudinal end region (18) of the pipette tip (10), as a coupling longitudinal end region (18), which opposes the pipetting longitudinal end region (16) in the axial direction, comprising a coupling shape, for coupling, preferably releasable coupling, to a coupling counter-shape of a pipette device, the pipette tip (10) comprising an outer hydrophobic region (32) on the outside (30) thereof and an inner hydrophobic region (26) on the inside (28) thereof, each having a quadratic roughness in a range of 100 nm to 1000 nm, preferably of 150 nm to 750 nm and particularly preferably of 200 nm to 500 nm, and having a peak-to-peak
