A mechanism (10) for an automated Karl Fischer (KF) titration system (1) includes a support console (6), a first vertical guide rail element (11), solidly attached to the support console, and a carriage unit (12), slidably constrained to the first vertical guide rail element, allowing the carriage unit a first degree of linear vertical mobility relative to the support console. The carriage unit holds a vial lift unit (13) with a lift platform (14) for a sample vial (18). The carriage unit, in a downward movement phase, lowers the lift platform from a starting position into an oven cavity of the titration system. A subsequent upward movement phase raises the lift platform to the starting position. A second vertical guide rail element, solidly connected to the lift platform and slidably constrained to the carriage unit, enables a second degree of linear vertical mobility of the lift platform.

Provided is a biochemical analyzer, which includes a housing, a sample feeding mechanism, a rotating mechanism, a pipetting mechanism, analyzing mechanisms, a sample discharging mechanism and a sample discharging box, wherein a sample feeding port and a sample discharging port are formed in the housing; the sample feeding mechanism is arranged in the housing and capable of introducing detection cards containing samples and reagents into the housing from the sample feeding port; the rotating mechanism is capable of clamping a plurality of detection cards and driving the detection cards to rotate; the sample feeding mechanism is capable of clamping the detection cards on the rotating mechanism; the pipetting mechanism is capable of mixing the samples with the reagents on the detection cards; the analyzing mechanisms are capable of analyzing the samples through detection rays; the sample discharging mechanism is used for removing the detection cards from the rotating mechanism.

A device (1) for storing reagent containers on several planes for an automatic analysis appliance. The device (1) comprises a pipetting device comprising a pipetting needle (2) for pipetting of reagents, a first device (3) comprising a plurality of first receiving positions (5) for reagent containers, wherein the first receiving positions (5) are arranged on a first plane, and a second device (4) comprising a plurality of second receiving positions (6) for reagent containers, wherein the second receiving positions (6) are arranged on a second plane.

A sample preparation cartridge for use with a sample preparation device, the cartridge includes a housing defining plural separate segments, at least one of said segments comprising a fixed section of a pipette component; and a moveable head comprising a pipette tip, the head being configured, in use, to be moved between a position in which the pipette tip is in sealed engagement with the fixed section of pipette component and a position in which pipette tip is positioned adjacent to another of said plural segments. With the present invention a disposable sample preparation cartridge and corresponding analytical reader can be provided in a very cost effective and simple manner whilst still ensuring high quality sample preparation for analysis.
