Description

MeciϊenkanaS for a laboratory

The invention relates to a Medienkana! for a laboratory device, in particular a media cell, media column, media traffic light or media stationary, for supplying a laboratory workstation with and / or for disposing of laboratory media.

The flexibility and mobility of laboratory facilities in a laboratory ensures that laboratory media such as water, wastewater, gas, compressed air, vacuum and electrical power connections are always available where they are needed. For this purpose, have media cells, media columns, Medϊenampein so-called. Media channels, run in the supply and disposal lines for the laboratory media, which are connected to the building side provided supply and Entsorgungsetnrichtungen.

A media rack may be in the form of a wall-mounted cell with a laboratory bench in front of it, a freestanding cell for a laboratory work table or double-workbench, or a tabletop cell. The media cell provides media-specific fittings and sockets and serves to accommodate different filing systems. In this case, the media cell can have a multiplicity of media panels with different equipment, from which the removal of the laboratory media, but also their disposal, can be fostered for waste disposal devices installed in the building.

In a media column suspended from a laboratory ceiling, the media channels run vertically through the media column,

A media traffic light has a plurality of grid cells suspended from the laboratory ceiling, which can be equipped with corresponding media panels on both sides, just as in the case of the median acid. The media panels run horizontally here and usually pass over several mostly mobile laboratory work tables. Ais media station is viewed in professional circles as a system for media supply and media disposal which is attached directly to the laboratory workstation by means of a clamping device and which is connected via a wiring harness to the corresponding supply and disposal systems installed on the building side.

The modular design plays a big role in all of these laboratory facilities, as this can save significant cost savings already in the planning phase of a laboratory,

Conventional media channels for use in the above-described laboratory devices, as disclosed, for example, in EP 0 800 865 A2 and DE 196 14 370 C1, are formed with the aid of two side stands arranged at a distance from one another, depending on the height of the laboratory device Cross beams are interconnected. Clamping devices, in which raised flanges of the respective media panels are clamped, are located on the crossbeams. The media and media disposal lines thereby run vertically through openings provided in the crossbeams or horizontally between adjacent crossbeams.

A disadvantage here is the relatively small depth of the media channels, which is uniform over the entire media cell, media column, media traffic or media station, which in particular electrical connections, which require a relatively large depth compared to, for example, gas fittings to a certain length from the media channels or protruding from the media panels. Furthermore, the retrofittability of conventional media channels with attachments, such as equipment carriers, shelves for reagents, tripod holder, etc. limited. Furthermore, one and the same media channel can not be used for different laboratory equipment since the constructional The requirements for media zones are different than those for media traffic lights, which results in higher installation, production and assembly costs.

DE 101 54 128 A1 discloses a line of media for a laboratory having a wall-shaped, vertically aligned instamentation element equipped with installation ducts and spreader connections above the height of a bench top of a laboratory bench. The ducts and manifolds are arranged inside the contour of the side uprights the table top facing narrow sides Verschiussteile or panels are mounted. In this media time stationary and pivotable panels are arranged alternately in a grid and attached to the side posts by screws.

The media channels described above are not limited to the forms shown here. Thus, the media channels, in particular their profile elements can be designed such that corresponding panels can be connected like a checkerboard with the Profüelement.

The conical linear cross-sectional shape in the upper region of the media channel makes more space available, in particular for electronic components, so that they can be accommodated in a hermetically sealed enclosure for protection against moisture to avoid short circuits. At the same time the tapered side of the media channel ensures that when using the media channel in a media cell, the full surface of the countertop can be used for the experimental procedure. To achieve these two goals, however, other cross-sectional shapes are conceivable, for example conical-convex shapes, Moreover, the connecting devices described above are not limited to resilient clamping devices. The person skilled in the art recognizes that other frictional or positive connection techniques can be used to achieve the same effect, namely an easy-to-use releasable attachment. Examples include snap, dovetail, possibly magnetic fasteners.
