Definitions
- the invention relates to a positioning device for a plurality of microreactors arranged in the form of a flat, rectangular micro-reactor disk, each consisting of at least one small cavity.
- Microreactors enable chemical reactions to be carried out in the smallest of spaces and with minimal use of reagents. Because of their very small dimensions, a large number of such microreactors are arranged in a matrix to form a microreactor disk.
- a microreactor disk consists of a silicon plate, into which a large number of small cavities are etched for carrying out individual reactions. Each individual cavity can be provided with additional features such as a sieve plate. Due to the miniaturization, a large number of individual reactions and analyzes can be carried out simultaneously. As a result, studies on the effects of new substances in the chemical and pharmaceutical field can be carried out much more economically and quickly.
- the cavities are usually filled first with a substance to be examined and then with one or more reagents.
- the reagents are drawn off, for example, through a sieve tray.
- the reaction products can then be analyzed chemically or physically.
- microreactor disk Because the dimension of the microreactor disk is still small, even for a large number of individual microreactors, and its low mechanical stability, a device is required with the aid of which the microreactor disk can be handled during the investigations. An almost imperative prerequisite for economical work with microreactor disks is extensive automation of necessary process steps, such as filling the substances into individual microreactors or pipetting or aspirating the reagents.
- the object of the invention is therefore to design a device for the simple handling and positioning of microreactor disks in such a way that the microreactor disks can be used reproducibly and safely during individual process steps and the metering or suctioning of reagents of individual microreactors is made possible.
- the positioning device has a carrier frame with a recess adapted to the shape of a microreactor disc and with a spring element pressing the microreactor disc laterally, and in that the carrier frame can be placed on a base plate.
- the microreactor disc can be inserted quickly and easily into the corresponding recess in the support frame.
- the spring element presses the microreactor disc laterally against the stops delimiting the recess and thereby securely fixed in the support frame.
- the microreactor disk is thus surrounded by the support frame on almost all sides during the following investigations.
- the carrier frame itself can be placed on a base plate, into which devices can already be integrated, which are required during the following process steps.
- the spring element has two curved spring legs protruding at right angles. Through the right-angled, curved spring legs! the microreactor disc is pressed laterally against the stops of the support frame provided for this purpose and reliably held in this position. Due to the small spring stroke, the microreactor disc can be quickly and easily inserted into the carrier frame.
- a holding frame which fixes the microreactor disc from above can be fastened on the carrier frame.
- Such a holding frame prevents the microreactor plate from falling out of the carrier frame while any process steps are being carried out.
- the holding frame additionally increases the stability of the microreactor pane and the support frame.
- the carrier frame has a bevel at least at one corner and the base plate has a shape adapted to it. Especially with a view to Automated handling of the microreactor disk located in the support frame is ensured by the beveling of the support frame and the corresponding shaping of the base plate, so that the support frame can only be positioned on the base plate in a constant orientation with respect to the base plate.
- the carrier frame has at least one recess or groove on one or more side surfaces, which are provided for simple, automatic handling. Extensive automation of individual process and transport steps is desirable for economic reasons. Safe gripping and transport of the support frame with automatic devices is considerably simplified by such recesses or grooves. In addition, such recesses or grooves can, in addition to the beveling of the support frame, enable confusion-free and precise positioning of the support frame not only on the base plate, but also in connection with other laboratory devices.
- the base plate has a 'of the shape of the microreactor plate recess adapted. If the microreactor plate held by the support frame, positioned on the base plate, the microreactor plate cover together with the carrier frame 1, the recess in the base plate and completely tight.
- the thus created cavity of the microreactor plate can as the filling or emptying of the individual microreactors are used for necessary process steps in the context of investigations'. This can result in frequently occurring process steps can be carried out automatically without the support frame having to be removed from the base plate.
- the base plate has a lateral opening for the recess. Via this opening, for example, a vacuum can be generated in the cavity formed by the recess in the base plate and the microreactor disc fixed in the support frame. This vacuum primarily makes it easy to fill the individual microreactors. Process steps such as sucking reagents out of the microreactors and washing the remaining substances are made considerably easier by the vacuum in the cavity.
- 1 is a carrier frame, a spring element, a microreactor disc and a holding frame in an exploded view
- Fig. 3 is a view of a base plate
- Fig. 4 is a view of the assembled and placed on the base plate, shown in Fig. 1.
- a support frame 1 shown in FIG. 1 has an essentially rectangular recess 2, which is provided for receiving a spring element 3 and a microreactor disc 4. Due to the shape of the recess 2 produced a limited by stops 5, circumferential support surface for the microreactor plate 4.
- a cylindrical-shaped extended area of the recess 2 serves to receive the spring member 3, which project at right angles Federsch 'grandchild 3a extend on two sides of the recess 2 along.
- the two spring legs 3a press the microreactor disc 4 against the opposite stops 5 of the carrier frame 1 and thus prevent the microreactor disc 4 from being unwantedly released from the carrier frame 1.
- a holding frame 6 which can be fastened to the carrier frame 1 has an opening which is adapted to the dimensions of the microreactor disc 4, so that in the assembled state only an unused edge, but not micro-chambers of the microreactor disc 4 is covered
- a slightly modified exemplary embodiment of a spring element 3 ′′, shown enlarged in FIG. 2, has two curved spring legs 3a ′ projecting at right angles.
- the spring element 3 ′ designed in this way ensures that the microreactor disk 4 is pressed on sufficiently reliably despite the small spring stroke of the individual spring legs 3a ′ to the stops 5 of the support frame 1 without fear of destruction or damage to the microreactor disc 4 as a result of excessive stress.
- FIG. 3 shows a view of an essentially cuboid base plate 7, the upper side of which has a recess 8 which is adapted to the support frame 1 and is slightly offset.
- a recess 8 of the base plate 7 at a right angle limiting projection 9 is used on two sides as a stop for the support frame 1 is for the Tr gerrah ⁇ men 1 Under the recess 8, a further, the dimensions of the microreactor plate 4 matched recess 10.
- the recess 10 has a lateral opening 11 which is designed as a hollow cylindrical connecting piece.
- the recess 10 becomes a closed cavity which has only the lateral opening 11.
- a vacuum can be created in the resulting cavity via this opening 11. This vacuum enables or facilitates individual process steps, such as filling or emptying the microreactors.
- the base plate 7 shows the base plate 7, the support frame 1 and the microreactor disc 4 in the assembled state.
- Two sides of the support frame 1 are flush with the outer sides of the base plate 7.
- the bevel 12 on a corner of the support frame 1 predetermines the orientation of the support frame 1 with respect to the base plate 7.
- a shape of the base plate 7 adapted to the bevel 12 of the support frame 1 prevents an incorrectly oriented support frame 1 from being able to be positioned flush on the base plate 7.
