Patentanmeldung
Zur Beaufschlagung der Probenplatte mit dem Probenfluid wird diese in ein Gehäuse eingebaut. Das Gehäuse weist hierzu eine mit einer Dichtung versehene Einbauöffnung auf, wobei die Dichtung an den Seitenkanten der eingebauten Probenplatte zum Eingriff kommt, so dass die Probenplatte und das Gehäuse gemeinsam eine dichte Reaktionskammer für das Probenfluid bilden. Zur Erzeugung der geforderten Dichtwirkung wird nach dem Einbau der Probenplatte ein Halterahmen in das Gehäuse eingesetzt, welcher die Dichtung verformt und so einen Anpressdruck der Dichtung an die Probenplatte erzeugt. Der aus den genannten Bauteilen bestehende und die Probenkammer bildende Verbund ist für den einmaligen Gebrauch bestimmt und wird nach dem Gebrauch entsorgt.to Applying the sample fluid to the sample plate is carried out in a housing built-in. The housing for this purpose has an installation opening provided with a seal, with the seal on the side edges of the built-in sample plate comes into engagement, so that the sample plate and the housing together a tight reaction chamber for form the sample fluid. To create the required sealing effect a holding frame is inserted into the housing after the sample plate has been installed, which deforms the seal and so a contact pressure of the seal generated on the sample plate. The one consisting of the named components and the composite sample chamber is for single use and is disposed of after use.
Die Aufgabe der Erfindung liegt darin, eine Probenplatte zum Einbau in eine Gehäusestruktur zwecks Bildung einer Reaktionskammer anzugeben, welche vergleichsweise einfach in ihrer Handhabung und möglichst wirtschaftlich in ihrer Verwendung ist.The The object of the invention is a sample plate for installation in a housing structure for the purpose Formation of a reaction chamber to indicate which comparative easy to use and as economical as possible Use is.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass mit der Probenplatte eine Dichtung fest verbunden ist, welche eine Anlagefläche für die Gehäusestruktur bildet. Die Integration der Dichtung in die Probenplatte führt vorteilhaft zu einer Baueinheit, die gleichzeitig die Funktion als Probenträger und die Dichtfunktion für die Reaktionskammer übernimmt. Hierdurch kann ein gesonderter Halterahmen, der einen Anpressdruck einer als gesondertes Bauteil ausgeführten Dichtung auf die Probenplatte erzeugt, eingespart werden. Damit kann die Fertigung eines Halterahmens entfallen, wodurch sich die Fertigungskosten für den die Reaktionskammer bildenden Bauteilverbund verringern und so die Wirtschaftlichkeit der Anwendung der Probenplatte steigt. Außerdem vereinfacht sich vorteilhafterweise die Handhabung der Probenplatte, welche nun einfach in die Gehäusestruktur eingesetzt werden kann, ohne dass ein weiterer Halterahmen montiert werden muss. Die Gehäusestruktur kann dabei ohne weiteres so ausgebildet werden, dass eine Dichtwirkung auch ohne einen zusätzlichen Halterahmen bereits durch Einsetzen der mit der Dichtung versehenen Probenplatte erzeugt wird.This The object of the invention solved, that a seal is firmly connected to the sample plate, which an investment area for the housing structure forms. The integration of the seal in the sample plate leads advantageously to a unit that also functions as a sample holder and the sealing function for the reaction chamber takes over. This can be a separate holding frame, the contact pressure a seal designed as a separate component on the sample plate generated, saved. This allows the production of a holding frame omitted, which increases the manufacturing costs for the reaction chamber Reduce component group and thus the economy of the application the sample plate rises. Moreover the handling of the sample plate is advantageously simplified, which is now simply in the housing structure can be used without the need for another holding frame must become. The housing structure can easily be designed so that a sealing effect even without an additional one Holding frame already by inserting the seal Sample plate is generated.
Nach erfolgter Beaufschlagung der Probenplatte mit dem Probenfluid und einer eventuellen Untersuchung der Proben kann die Probenplatte der Gehäusestruktur auf einfache Weise wieder entnommen werden. Damit kann die Gehäusestruktur vorteilhafterweise mehrfach verwendet werden, indem eine neue Pro benplatte eingesetzt wird. Eine eventuelle Beschädigung der Dichtung beim Ausbau der Probenplatte hat dabei keinen Einfluss auf die Dichtigkeit der Reaktionskammer, weil die neue Probenplatte mit einer eigenen integrierten Dichtung ausgestattet ist und die alte Probenplatte mit samt der Dichtung entsorgt wird.To acted upon the sample plate with the sample fluid and The sample plate can be used to examine the samples the housing structure can be removed again in a simple manner. So that the housing structure advantageously be used several times by a new Pro benplatte is used. Possible damage to the seal during removal the sample plate has no influence on the tightness of the Reaction chamber because the new sample plate with its own integrated Is equipped and the old sample plate with the Seal is disposed of.
Gemäß einer Ausgestaltung der Probenplatte ist vorgesehen, dass die Anlagefläche eben ausgebildet ist. Hierdurch lässt sich vorteilhafterweise eine besonders einfache Geometrie der Dichtung erreichen, die dadurch besonders einfach herstellbar ist.According to one The design of the sample plate is such that the contact surface is flat is trained. This leaves a particularly simple geometry of the seal is advantageous achieve, which is particularly easy to manufacture.
Es ist z. B. vorteilhaft, wenn die Dichtung auf der die Aufnahmebereiche tragenden Seite der Probenplatte liegt und dabei das Array der Aufnahmebereiche umgibt. Hierbei kann eine Dichtung besonders einfacher Geometrie auf die ebene Seite der Probenplatte aufgebracht werden und kann dabei gleichzeitig als Umrandung für das Array der Aufnahmebereiche dienen. Dies ermöglicht auch eine besonders einfache Handhabung der Probenplatte im Zusammenwirken mit einer als Low-cost-Teil ausgebildeten Gehäusestruktur in Form einer einfachen Gehäuseplatte. Diese Gehäusestruktur besitzt lediglich eine ebene Auflagefläche, die gegen die Dichtung gedrückt wird, wobei die Höhe der Dichtung gleichzeitig die Höhe der sich zwischen der Probenplatte und der Gehäuseplatte befindlichen Probenkammer bestimmt. Eine Probenflüssigkeit kann vor Montage der Gehäuseplatte direkt auf die Probenplatte gegeben werden, da die Dichtung bereits die Seitenwände der Kammer bildet.It is z. B. advantageous if the seal on the receiving areas load-bearing side of the sample plate and the array of recording areas surrounds. Here, a seal can have a particularly simple geometry can be applied to the flat side of the sample plate and can at the same time as a border for the array of the recording areas serve. this makes possible also a particularly simple handling of the sample plate in interaction with a housing structure designed as a low-cost part in the form of a simple Housing plate. This housing structure only has a flat contact surface that is against the seal depressed being, the height the height of the seal the sample chamber located between the sample plate and the housing plate certainly. A sample liquid can before mounting the housing plate be placed directly on the sample plate as the seal is already the side walls the chamber forms.
Eine Variante der zuletzt beschriebenen Ausführungsform sieht vor, dass die Dichtung als Schicht insbesondere aus einem Lack wie Fotolack auf dem Probenträger ausgeführt ist, welche im Bereich des Arrays der Aufnahmebereiche den Probenträger freigibt. Die Eigenschaften der Schicht müssen dabei gewährleisten, dass eine Dichtwirkung zwischen der Gehäusestruktur und der Schicht erzeugt werden kann. Hierfür werden insbesondere eine gewisse Elastizität der Schicht und eine genügende Maßhaltigkeit der Anlagefläche gefordert. Wird die Schicht beispielsweise aus Fotolack gebildet, sind die genannten Bedingungen erfüllt. Die Bildung der Dichtung aus einer Schicht hat den Vorteil, dass aufgrund des Anhaftens der Schicht auf der Probenplatte eine Fixierung der Dichtung auf der Probenplatte bereits durch den Herstellungsprozess selbst erfolgt, so dass die Dichtung nach ihrer Herstellung nicht mehr mit der Probenplatte verbunden werden muss.A variant of the last-described embodiment provides that the seal is designed as a layer, in particular made of a lacquer, such as photoresist, on the sample carrier, which clears the sample carrier in the area of the array of the receiving areas gives. The properties of the layer must ensure that a sealing effect can be created between the housing structure and the layer. For this purpose, a certain elasticity of the layer and a sufficient dimensional stability of the contact surface are required. If the layer is formed from photoresist, for example, the conditions mentioned are fulfilled. The formation of the seal from a layer has the advantage that due to the adhesion of the layer to the sample plate, the seal is already fixed on the sample plate by the manufacturing process itself, so that the seal no longer has to be connected to the sample plate after its manufacture.
Eine andere Ausgestaltung der Erfindung sieht vor, dass sich auf dem Probenträger an das Array der Aufnahmebereiche ein Zulaufbereich und ein Ablaufbereich für das Probenfluid anschließen, welche ebenfalls von der Dichtung umgeben sind. Der Zulaufbereich und der Ablaufbereich ermöglichen vorteilhaft ein gleichmäßiges Anströmen des Arrays der Aufnahmebereiche auf der Probenplatte mit dem Probenfluid. Die Herstellung des Zulaufbereiches und des Ablaufbereiches erfolgt während der Herstellung der Probenplatte und erfordert daher vorteilhafterweise keinen zusätzlichen Fertigungsaufwand. Nach Einsetzen der Probenplatte in die zugehörige Gehäusestruktur kommunizieren der Zulaufbereich und der Ablaufbereich jeweils mit einem in die Gehäusestruktur integrierten Einlass und Auslass für das Probenfluid.A another embodiment of the invention provides that on the sample carrier an inlet area and an outlet area to the array of the receiving areas for the Connect sample fluid, which are also surrounded by the seal. The inflow area and the drain area allow advantageous a steady flow towards the Arrays of the receiving areas on the sample plate with the sample fluid. The inlet area and the outlet area are manufactured while the preparation of the sample plate and therefore advantageously requires no additional Production expense. After inserting the sample plate into the associated housing structure the inlet area and the outlet area each communicate with one in the case structure Integrated inlet and outlet for the sample fluid.
Die Probenplatte kann vorteilhaft auch mit der Dichtung durch eine Klebeverbindung verbunden sein. Die Wahl einer Klebeverbindung zwischen Dichtung und Probenplatte ermöglicht vor teilhaft eine große Freiheit in der Auswahl der Werkstoffe für Dichtung und Probenplatte.The Sample plate can also advantageously be connected to the seal by an adhesive connection be connected. The choice of an adhesive connection between the seal and sample plate enables a big part ago Freedom in the choice of materials for seals and sample plates.
Eine andere Ausführungsform der Erfindung sieht vor, dass die Probenplatte mit der Dichtung einteilig hergestellt ist. Die Verbindung zwischen Probenplatte und Dichtung erfolgt dabei vorteilhafterweise schon bei der Herstellung, so dass ein nachgeordneter Montageschritt eingespart werden kann.A other embodiment The invention provides that the sample plate with the seal is made in one piece. The connection between the sample plate and sealing advantageously takes place during manufacture, so that a subsequent assembly step can be saved.
Eine Weiterbildung der letztgenannten Ausführungsform ist darin zu sehen, dass die Probenplatte mit der Dichtung als Mehrkomponentenspritzgießteil mit der Probenplatte als eine Komponente und der Dichtung als weitere Komponente hergestellt ist. Hierbei können vorteilhaft die Werkstoffe so ausgewählt werden, dass sie jeweils der Funktion als Probenplatte und der Funktion als Dichtung in optimaler Weise gerecht werden.A Further development of the latter embodiment can be seen in that the sample plate with the seal as a multi-component injection molded part the sample plate as one component and the seal as another Component is made. Here, the materials can be advantageous so selected that they each have the function as a sample plate and the function as a seal in an optimal way.
Gemäß einer besonderen Ausgestaltung der Erfindung weist die Probenplatte die Standardmaße für Objektträger von 76 × 26 × 1 mm auf. Die Probenplatte kann dann vorteilhaft unter Verwendung eines Massenproduktes hergestellt werden, welches zu günstigen Konditionen zugekauft werden kann.According to one Special embodiment of the invention has the sample plate Standard dimensions for slides from 76 × 26 × 1 mm. The sample plate can then advantageously be used using a mass product can be produced, which for cheap Conditions can be bought.
