Description

Gegenstand der Erfindung ist eine Vorrichtung zum Thermostatisieren und Mischen des Inhaltes von Gefäßen einer Mikrotitrationsplatte für immunologische Tests.The invention relates to a device for Thermostatizing and mixing the contents of vessels a microtitration plate for immunological tests.

Bei immunologischen Tests, wie z. B. bei Enzyme-Linked- Immuno-Sorbent-Assays (ELISA) sind auf den Gefäßwänden einer Mikrotitrationsplatte Antigene (Antikörper) oberflächenfixiert, mit denen sich während der ersten Inkubationszeit die in der Probe vorhandenen Antikörper (Antigene) binden. Nach Auswaschen nicht gebundener Probenbestandteile wird Enzym-Konjugat dosiert. Nach Ablauf der zweiten Inkubation wird überschüssiges Konjugat durch Waschen entfernt und Substrat dosiert. Nach Ablauf der dritten Inkubation wird die Umsetzung gestoppt. Alle Schritte werden bei einer bestimmten Temperatur durchgeführt. Die Gefäße müssen also thermostatisiert werden. Nachteilig ist nicht nur das aufwendige Thermostatisieren der Mikrotitrationsplatte, sondern auch die verhältnismäßig lange Inkubationszeit. Hier will die Erfindung Abhilfe schaffen.In immunological tests, such as. B. with enzyme-linked Immunosorbent assays (ELISA) are on the vessel walls a microtitration plate antigens (antibodies) surface-fixed, with which during the first Incubation time the antibodies present in the sample Bind (antigens). Not washed after washing Enzyme conjugate is dosed into sample components. After expiration the second incubation is carried out by excess conjugate Washing removed and substrate dosed. After the expiration of the Third incubation, the implementation is stopped. All Steps are taken at a certain temperature carried out. The vessels must therefore be thermostatted will. It is not only the complex that is disadvantageous Thermostatizing the microtitration plate, but also the relatively long incubation period. Here she wants Invention to remedy the situation.

Die Aufgabe wird durch eine Vorrichtung gelöst, die dadurch gekennzeichnet ist, daß eine der Fläche der Mikrotitrationsplatte entsprechende Haube als allseits geschlossener Hohlraum ausgebildet ist, in den eine Gasleitung mündet und dessen der Mikrotitrationsplatte zugewandte Begrenzungswand mit Gasaustrittsöffnungen versehen ist, die exzentrisch in bezug auf die Gefäßachsen angeordnet und unter einem Winkel α auf die Oberflächen der Flüssigkeiten in den Gefäßen gerichtet sind.The object is achieved by a device which is characterized in that a hood corresponding to the surface of the microtitration plate is designed as a cavity which is closed on all sides, into which a gas line opens and whose boundary wall facing the microtitration plate is provided with gas outlet openings which are eccentric with respect to the Vessel axes are arranged and directed at an angle α to the surfaces of the liquids in the vessels.

Die Vorrichtung bietet den Vorteil, daß die in den Gefäßen befindliche Flüssigkeit durch thermostatisiertes Gas in eine zirkulare Bewegung versetzt wird, wodurch nicht nur die Thermostatisierung der Flüssigkeit, sondern auch im Wandbereich die Bindung und Umsetzung der Reagenzien mit den Proben verbessert wird. Daraus resultieren kürzere Inkubationszeiten und damit kürzere Testzeiten.The device has the advantage that the in the vessels liquid inside by thermostated gas  a circular movement is offset, which not only the thermostatting of the liquid, but also in the Wall area with the binding and implementation of the reagents the samples is improved. This results in shorter ones Incubation times and therefore shorter test times.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt:In the following, the invention is based on only an execution path drawings closer explained. It shows:

Fig. 1 die Vorrichtung zum Thermostatisieren und Mischen über einer Mikrotitrationsplatte angeordnet in perspektivischer Darstellung, Fig. 1, the device for thermostatting and mixing over a microtitration plate arranged in a perspective view;

Fig. 2 eine Gasaustrittsöffnung in ein einzelnes Gefäß geschnitten und Fig. 2 cut a gas outlet opening in a single vessel and

Fig. 3 eine Gasaustrittsöffnung in ein einzelnes Gefäß in Draufsicht. Fig. 3 shows a gas outlet opening in a single vessel in plan view.

Die Vorrichtung besteht im wesentlichen aus einer Haube 1, deren Abmessung der Fläche der Mikrotitrationsplatte 2 mit den Gefäßen 7 entspricht und die mit einem Hohlraum 3 versehen ist, in den eine Gasleitung 4 für thermostatisiertes Gas, z. B. Luft von 30° bis 50°C mündet. Die der Mikrotitrationsplatte 2 zugewandte Begrenzungswand 5 für den Hohlraum 3 der Haube 1 ist mit Gasaustrittsöffnungen 6 versehen. Der Hohlraum 3 dient als Gasverteiler für die Gasaustrittsöffnungen 6. Die Gasaustrittsöffnungen 6 können als Düsen oder Kanülen ausgebildet sein. Diese sind in der Begrenzungswand 5 so plaziert, daß sie exzentrisch in bezug auf die Gefäßachsen 8 angeordnet sind. Der Luftstrom erzeugt beim Auftreffen auf die Flüssigkeitsoberfläche 10 eine Einbuchtung 11 auf dem Radius R. Die Düsenachse ist in bezug auf die Oberfläche 10 um den Winkel α geneigt. Dabei kann der Abstand der Gasaustrittsöffnung von der Gefäßwand in radialer Richtung 0,2 bis 0,5 Gefäßradien betragen und der Winkel α, unter dem die Gefäßaustrittsöffnung zur Flüssigkeitsoberfläche hin geneigt ist, 40° bis 80°. The device consists essentially of a hood 1 , the dimension of which corresponds to the area of the microtitration plate 2 with the vessels 7 and which is provided with a cavity 3 into which a gas line 4 for thermostatted gas, for. B. air from 30 ° to 50 ° C opens. The boundary wall 5 for the cavity 3 of the hood 1 facing the microtitration plate 2 is provided with gas outlet openings 6 . The cavity 3 serves as a gas distributor for the gas outlet openings 6 . The gas outlet openings 6 can be designed as nozzles or cannulas. These are placed in the boundary wall 5 so that they are arranged eccentrically with respect to the vessel axes 8 . The air flow creates an indentation 11 on the radius R when it hits the liquid surface 10 . The nozzle axis is inclined by the angle α with respect to the surface 10 . The distance of the gas outlet opening from the vessel wall in the radial direction can be 0.2 to 0.5 vessel radii and the angle α at which the vessel outlet opening is inclined towards the liquid surface can be 40 ° to 80 °.

Durch Reibung der Luft mit der Flüssigkeitsoberfläche 10, vorrangig bei 11, entstehen zwei sich überlagernde Strömungen der Flüssigkeit, und zwar eine kreisförmige Strömung 12 um die Gefäßachse 8 und eine nach unten in die Flüssigkeit gerichtete bogenförmige Strömung 9. Durch diese sich überlagernden Strömungen 12 und 8 wird die Flüssigkeit intensiv an der Gefäßwand vorbeigeführt. Damit kann die Inkubationszeit erheblich verkürzt werden, d. h. die chemische Reaktion zwischen den Molekülen der Flüssigkeit und der Wand beschleunigt werden. Die Inkubationszeit des ELISA-Tests geht zurück und der Probendurchsatz der ELISA-Testgeräte nimmt zu.The friction of the air with the liquid surface 10 , primarily at 11 , creates two superimposed flows of the liquid, namely a circular flow 12 around the vessel axis 8 and an arcuate flow 9 directed downwards into the liquid. Due to these superimposed flows 12 and 8 , the liquid is guided intensively past the vessel wall. The incubation time can thus be shortened considerably, ie the chemical reaction between the molecules of the liquid and the wall can be accelerated. The incubation period of the ELISA test is decreasing and the sample throughput of the ELISA test devices is increasing.
