Embodiment Construction

[0039] The dosing device 1 is equipped with a plurality of dosing units 2 which are each able to take in and also emit a fluid sample. The fluid samples to be absorbed are usually provided in a matrix-like distribution within a correspondingly constructed carrier matrix, such carrier matrices being in particular so-called microtiter plates. The carrier matrix has a plurality of receiving recesses, in which a fluid sample can be provided in each case. By means of the dosing unit 2 , a fluid sample can be removed from the receiving recess and subjected to subsequent processing, for example analysis. The dosing device 1 can also be used to dispense treated or untreated fluid samples into such a carrier matrix for storage or further processing.

[0040] The dosing device 1 is used, for example, in medical technology, in the field of pharmacy and / or in any biological or biochemical procedure.

[0041] The dosing units 2 are expediently designed identically to one another. They e...

Abstract

The invention relates to dosing equipment which realizes quantitative absorption and / or conveying of a fluid sample. The dosing equipment comprises a dosing head which can operate through a positioning device. The dosing head is provided with a plurality of dosing units which are distributed in a matrix manner. Each dosing unit is provided with an electrically controllable driving device and is provided with a driving contact member which is configured at a back-side end segment. Furthermore the dosing head is provided with a control head with an electric control device which can be connected with a main control device. The control head is provided with a control contact member which is configured at the lower side, wherein the control contact member is connected with the control device. The control head is a structural unit which is independent from the dosing device and can be mounted on the dosing device and / or detached from the dosing device, wherein electric contact or separation between the control contact member and the driving contact member is correspondingly performed simultaneously.

Description

technical field [0001] The invention relates to a dosing device for dosing and / or dispensing a fluid sample, with a dosing head that is movable and positionable by a positioning device, the dosing head having multiple A dosing device with dosing units arranged side by side in a matrix distribution, the dosing units having rear end sections oriented in the same direction as one another and each equipped with a movable dosing device and associated with the dosing device drive means, wherein the dosing head is additionally equipped with a control device, which has a control means that enables the independent operational control of the drive means of the individual dosing units, wherein the control means are designed to be controlled by an electronic main control Device manipulation. Background technique [0002] Such a dosing device is known, for example, from DE 19835833 A1, which allows a fluid sample to be taken up in doses from a carrier matrix and / or to dispense a fluid s...
