The invention relates to a pipetting device () for an automatic analysis appliance, wherein the pipetting device () comprises a pipetting needle () with a longitudinal axis (), and a device () for moving the pipetting needle (). The pipetting device () further comprises a holder () for the pipetting needle (), which holder () is mounted on the movable device () and to which holder the pipetting needle () is releasably connected, and a vibration generator which can set at least the tip of the pipetting needle () in vibration, wherein the vibration generator is mounted on the movable device ().

Pipetting device

An apparatus for separating rod-like or spherical agitating elements in an automatic analyzer allows quick and error-resistant separation and automated charging of cuvettes with the agitating elements. For this purpose, it comprises a lever provided with a bore, wherein the bore is configured such that it can accommodate one of the agitating elements. The bore, in a first position of the lever, is arranged beneath an entry opening and, in a second position of the lever, is arranged above an exit opening, wherein the lever, in the second position, closes the entry opening.

Apparatus for separating spherical or cylindrical objects

The invention relates to a rotatable device () for transporting reaction vessels in an automatic analysis apparatus, said device () comprising a circular base plate (), and a number of holders () which are connected to the base plate (), are preferably made of a plastic and comprise the receiving positions () for the reaction vessels.

Device for transporting reaction vessels

A closure system for a holder for a reaction vessel in an automatic analysis apparatus includes a lid secured movably on a retainer element, wherein the lid closes an opening of the holder in a closed position and opens the opening of the holder in an open position. The closure system further includes a restoring element configured to, depending on the position of the lid, exert a restoring force in the direction of the closed position or of the open position.

Closure system for reagent vessel receiving positions in an automatic analysis apparatus

The invention relates to a retaining device () for a hollow needle () of a pipetting device in an automatic analysis apparatus. The retaining device () comprises a first retaining element (), which can be secured releasably on a base plate that is movable in an automated manner, and a second retaining element (), which is connected to the first retaining element (), wherein at least one bearing bushing () is provided, which is fixed between the retaining elements () and in which the hollow needle () is mounted.

Retaining device for a pipetting needle

A closure device including a first and second closure element, the first closure element, which has an opening, being mounted on the opening of a container to be closed and the second closure element being movably connectable to the first closure element, the first closure element of the device having on the bottom surface facing the container a raised edge, which encircles the opening and has a sharp-edged region and a blunt region.

Closure device for a reagent container

The invention relates to an appliance for opening and closing a reagent-container stopper in a partially or fully automatic analysis apparatus, and to the method, which is applied by means of this appliance, for opening and closing a reagent-container stopper in a partially or fully automatic analysis appliance.

Closure appliance for reagent containers

An exchangeable oscillating pipette needle for an automatic analyzer for examining biological body fluids is provided, in which the analyzer has a holder provided with a tension spring, and with which the oscillating arm, carrying the pipette needle and resting on a knife-edge bearing, is fixed in a stationary position and is releasably connected.

Cap for a reagent container

A flow damper for cleaning stations, in particular for cleaning pipettor tips, is described, a cleaning liquid being introduced into the cleaning station through a pipettor needle and flowing around the pipettor tip before it is conducted away out of the cleaning station. In order to avoid wetting of the isolation surfaces of the pipettor needle and a level detector electrode, if provided, there are provided, according to the invention, in the cleaning station at least one screen having a preferably central entry orifice for the jet of liquid emerging from the pipettor needle and a device for diverting the liquid flow in the direction essentially opposite that of the entering jet of liquid. Furthermore, a plurality of exit orifices, preferably arranged radially around the entry orifice, for the diverted liquid flow are formed in the at least one screen.
