Abstract: The present disclosure relates to a device for preparing, in an automated manner, at least one sample for analysis by means of matrix-assisted laser desorption ionization in combination with a mass spectrometric analysis, and to a corresponding method. The device comprises a sample-receiving area which is surrounded by a housing and forms an internal volume which is closed off from the surroundings, a loading/unloading device for introducing the sample into the sample-receiving area and for removing the sample from the sample-receiving area, a heating unit configured to heat at least the sample-receiving area, and a vacuum device configured to generate a vacuum in the sample-receiving area.

Abstract: A capillary dispenser includes at least one plunger-cylinder unit having a cylinder module and a plunger module disposed together on an axis. The cylinder module has an inner cylinder that is pneumatically connected to at least one capillary. The plunger module includes a hollow plunger that is closable on one side and is movable in the inner cylinder along the axis between an upper end position and a lower end position of the plunger module.

Abstract: A suction device for a matrix array of pipette tips includes a tray configured to hold a liquid dispensed by the pipette tips. The tray includes an open-pore tray bottom. A suction tray cooperates with the open-pore tray bottom so as to form a vacuum chamber with the open-pore tray bottom forming a constituent of the vacuum chamber. A suction element is indirectly connected to the tray via the vacuum chamber so as to be configured to actively draw liquid over an entire surface into the vacuum chamber by suction via the tray bottom.
