Abstract: A pipetting device comprising a head and a nozzle with a longitudinal axis mounted to the head is disclosed. An actuator member is arranged around and partially covering the nozzle and coupled to the head or to the nozzle. The actuator member and the nozzle move with respect to each other along the longitudinal axis. A contact member is coupled to and arranged around and partially covering the actuator member. The contact member and the actuator member move with respect to each other. The contact member comprises a rim for contacting a container. The actuator member comprises a rim for opening a cap of the container when the contact member is in contact with the container. The actuator member and the contact member move with respect to each other creating a passage through the cap when the nozzle and the actuator member move with respect to each other.

Abstract: A positioning system for positioning a consumable rack in a diagnostic system is disclosed. The positioning system comprises a rack comprising an upper surface comprising holding positions and a receiving compartment comprising a rectangular chassis comprising front, rear, and two lateral sides. The receiving compartment comprises a holding structure coupled to the chassis to move between first and second positions. The rack comprises sidewalls. At least three sidewalls have a center alignment element. The chassis comprises three chassis alignment elements on the rear and two lateral sides. The holding structure comprises a corner push element between the chassis front and lateral sides to push against a side edge of the rack between two sidewalls when the holding structure is moved from the first position towards the second position forcing the three alignment elements against a chassis alignment element and laterally holding the rack in position by the chassis alignment elements.
