Abstract: An automated laboratory system includes a work area with a plurality of predefined workstations. Each of the plurality of predefined workstations occupies a footprint of a standardized microtiter plate. At least one tool holder is structured to move tools above the work area and at least one transport tool is structured to be moved by the tool holder in order to relocate laboratory items within the work area. At least one pipetting tool is structured to be moved by the tool holder in order to pick up and release pipette tips. A holder for pipette tip carriers includes at least one carrying apparatus defining a rectangular through-opening, and a support apparatus connected to the carrying apparatus. An electronic control apparatus is connected to the tool holder and structured to control movements of the transport tool and at least one pipetting tool by the tool holder.

Abstract: A centrifuge rotor (10) includes a closure (32) between a lower part (12) of the centrifuge rotor (10) and a cover (14). The centrifuge rotor has been improved such that proper single-handed operation is made possible. In particular, the closure (32) can be closed and detached again using just one hand. The cover (14) includes a circular cut-out (20) for fastening the centrifuge rotor (10) in a centrifuge. The cover (14) is attached to the lower part (12) by levers having a concave shaping (66). The cover (14) and the levers cooperate to provide a visual indication whether the cover is properly closed.

Abstract: A pipette with an adjustable dosing volume comprises a housing connected to at least one seat configured to releasably hold a pipette tip. A displacement device is positioned within the housing and configured to aspirate and discharge liquid from the pipette tip. A stroke rod is coupled to the displacement element and configured to be longitudinally displaced relative to the housing to displace the displacement device. A catch sleeve is rotatably mounted within the housing and is connected to the stroke rod. An adjusting sleeve configured to engage a transducer shaft that is rotatably mounted within the housing and comprises a countershaft of a gearbox that is configured to be shifted between different shift stages. Each shift stage comprises different gear ratios between a rotational speed of the adjusting sleeve and a rotational speed of the catch sleeve. The different gear ratios enable coarse volume adjustment and fine volume adjustment.

Abstract: A centrifuge includes a swing rotor. Rotor arms of the swing rotor have recesses into which hangers of the swing rotor at least partially swing in a swung-out state. As a result, the centrifuge container and thus also the centrifuges are more compact, because the swinging-out requires less space. An inertial mass of the swing rotor is reduced due to the recesses provided therein, whereby energy consumption, primarily when starting the centrifuge, is significantly reduced.

Abstract: A centrifuge (10) and a method for preventing the ignition of combustible tempering media in centrifuges (10) after a crash of the centrifuge rotor are presented. Ignition is prevented by the release of a protective gas in the event of a crash. More precisely, the released protective gas forms a flow that displaces the oxygen, distributes the escaping tempering medium and fundamentally changes the momentary ratio of the concentration of oxygen to tempering medium in such a manner that no ignition can take place either inside or outside the centrifuge (10). This means that combustible tempering media can also be used without safety concerns within the scope of controlling the temperature of centrifuges (10).

Abstract: A pipette with an adjustable dosing increment, a display apparatus, a drawing lever to draw liquid into a syringe, and a control button to discharge liquid in steps from the syringe, and the syringe actuated by means of the pipette, wherein the syringe is releasably connected to the pipette, the dosing increment is optionally set, or the previously set dosing increment is retained, the dosing volume set by the dosing increment is displayed by means of the display apparatus, liquid is sucked into the syringe by actuating the drawing lever, the respective position of a drive element of a drive mechanism of the pipette for filling and draining the syringe when the drive element is shifted along a path is detected, the possible maximum number of dosing steps with the set dosing increment without refilling the syringe after executing the reverse stroke starting from the position of the drive element reached at the end of filling is determined and displayed by means of the display apparatus, after the syringe is completely or partially filled with liquid, the reverse stroke is executed by actuating the control button at least once, dosing steps are executed by actuating the dosing button, the executed dosing steps are counted, the number of executed dosing steps and/or the number of still possible dosing steps without refilling the syringe are determined and displayed by means of the display apparatus, and after executing the maximum possible number of dosing steps without refilling the syringe, either the syringe is removed from the pipette, or steps 1.2 to 1.8 are repeated with same syringe, wherein in step 1.8, the total number of dosing steps performed with the syringe with the set dosing increments is counted, and/or the number of still possible dosing steps without refilling the syringe is determined and displayed by means of the display apparatus.

Abstract: A pipette comprises a pipette housing comprising an upper end and a lower end, a nipple configured to contact and retain a pipette tip, a drive apparatus configured to aspirate a liquid specimen into the pipette tip and expel the liquid specimen from the pipette tip, and an ejection apparatus. The ejection apparatus comprises a curved support rotatably mounted within the pipette housing, an ejection rod, a first sensing element positioned on the ejection rod and configured to be guided on a first curve on a perimeter of the curved support, and an operating element coupled to the curved support and configured to rotate relative to the pipette housing. The ejection apparatus is configured to rotate the curved support out of a start position by rotating the operating element. The first curve displaces the first sensing element downward a the ejection rod moves the pipette tip off of the nipple.
