Description
Die Erfindung betrifft einen Kryostat mit einer Kryostatkammer in der ein Mikrotom zum Schneiden von gefrorenen Präparaten angeordnet ist, gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a cryostat with a cryostat chamber in the a microtome for cutting frozen preparations is arranged, according to the preamble of claim 1
Derartige Kryostate werden verwendet, um mit einem Mikrotom gefrorene Präparate für eine anschließende Betrachtung mit einem Mikroskop zu schneiden. Die zu schneidenden Präparate werden auf eine bestimmte vorgegebene Temperatur gekühlt werden. Die Temperaturen liegen hierbei in der Regel zwischen –10°C und –50°C. Um die Temperaturkonstanz zu gewährleisten, werden die Mikrotome in aufwendig gekapselten Kryostatkammern angeordnet und diese entsprechend gekühlt.such Cryostats are used to prepare microtome-frozen specimens for subsequent viewing to cut with a microscope. The preparations to be cut open a certain predetermined temperature to be cooled. The temperatures are usually between -10 ° C and -50 ° C. To the temperature stability to ensure, the microtomes are arranged in elaborately encapsulated Kryostatkammern and these cooled accordingly.
Um ein sicheres Arbeiten zu gewährleisten, wird die Kryostatkammer mit Lampen beleuchtet. Dies hat jedoch den Nachteil, dass diese Lichtquellen Wärme erzeugen und so die für den Schnitt des Präparats entscheidende Temperaturkonstanz gefährdet ist.Around will ensure a safe working illuminated the cryostat chamber with lamps. However, this has the disadvantage that these light sources heat produce and so for the the section of the preparation decisive temperature stability is at risk.
Außerdem hat es sich herausgestellt, dass sich die recht groß dimensionierten Lichtquellen nur schlecht reinigen lassen.Besides, has It turned out that the quite large-sized light sources can only be cleaned poorly.

Die
Es ist daher Aufgabe der vorliegenden Erfindung, die Beleuchtung der Kryostatkammer so zu verbessern, dass eine höhere Temperaturkonstanz innerhalb der Kammer gegeben ist.It is therefore an object of the present invention, the lighting of Cryostat chamber to improve so that a higher temperature stability within the chamber is given.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst. Weitere vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.These The object is achieved by the specified in the characterizing part of claim 1 features solved. Further advantageous developments are the subject of the dependent claims.
Die Erfindung zeichnet sich dadurch aus, dass die Beleuchtungseinrichtung als Lichtquelle mehrere LEDs, vorzugsweise Weißlicht-LEDs, aufweist.The Invention is characterized in that the illumination device as a light source, a plurality of LEDs, preferably white light LEDs.
Mit den LEDs wird eine kompakte Bauform, eine sehr geringe Wärmeabstrahlung und eine gute Reinigungs- und Desinfektionsmöglichkeit erreicht. Außerdem lassen sich die LEDs durch ihre Raumform auch sehr gut gegen Spritzwasser schützen.With The LEDs are a compact design, a very low heat radiation and achieved a good cleaning and disinfection. In addition, let The LEDs are also very good against splashing water due to their spatial form protect.
Mehrere LEDs sind zu einem Beleuchtungsmodul zusammengefasst. Damit wird eine erhöhte Leuchtdichte bei einer kompakten Bauform erreicht. Ferner lassen sich so auch die elektrischen Kontakte der LEDs sehr einfach gegen Feuchtigkeit bzw. Spritzwasser schützen.Several LEDs are grouped together to form a lighting module. This will be an increased luminance achieved in a compact design. Furthermore, it is also possible the electrical contacts of the LEDs are very easy against moisture or splash water.
In einer Weiterbildung weist das Beleuchtungsmodul ein Gehäuse mit einem Steckeranschluss zur Stromversorgung auf. Damit wird erreicht, dass das Beleuchtungsmodul über den Steckeranschluss austauschbar in der Kryostatkammer angeordnet werden kann. So können, je nach Bedarf, einzelne oder mehrere Beleuchtungsmodule in vorbereitete Steckeraufnahmen in der Kryostatkammer austauschbar angeordnet werden.In In a further development, the lighting module has a housing a plug connection to the power supply. This is achieved that the lighting module over the plug connection interchangeably arranged in the cryostat chamber can be. So, as needed, single or multiple lighting modules in prepared Plug receptacles are arranged interchangeably in the cryostat chamber.
In einer weiteren Ausgestaltung der Erfindung sind mehrere Beleuchtungsmodule elektrisch mit einer gemeinsamen Stromversorgung verbunden. Diese Stromversorgung ist vorzugsweise außerhalb der Kryostatkammer vorgesehen, so dass neben einem minimierten Aufwand hier auch eine reduzierte Wärmeentwicklung realisiert ist.In Another embodiment of the invention is a plurality of lighting modules electrically connected to a common power supply. These Power supply is preferably outside the cryostat chamber provided so that in addition to a minimal effort here also a reduced heat development is realized.
In einer Weiterbildung der Erfindung ist eine Schaltungsanordnung zum An- und Abschalten einzelner und/oder mehrerer Beleuchtungsmodule vorgesehen. Je nach Anwendung können so einzelne Bereiche innerhalb der Kryostatkammer beleuchtet werden.In a development of the invention is a circuit arrangement for Switching on and off of individual and / or several lighting modules intended. Depending on the application can so individual areas are illuminated within the cryostat chamber.
In einer vorteilhaften Weiterbildung hat die Schaltungsanordnung zusätzlich die Funktion eines Dimmers für einzelner und/oder mehrerer Beleuchtungsmodule.In an advantageous development, the circuit arrangement additionally has the Function of a dimmer for single and / or multiple lighting modules.
Dadurch ist ebenfalls eine individuelle Ausleuchtung der Kryostatkammer möglich.Thereby is also an individual illumination of the cryostat chamber possible.
In einer Weiterbildung der Erfindung ist am Kryostat ein Schalter angeordnet und mit der Schaltungsanordnung elektrisch verbunden ist, wobei der Schalter beim Öffnen und/oder Schließen der Kryostatkammer einzelne und/oder mehrere Beleuchtungsmodule automatisch schaltet und/oder dimmt. Mit dieser Funktion wird erreicht, dass beim Öffnen der Deckels oder der Scheibe durch eine Bedienperson automatisch das Beleuchtungslicht innerhalb der Kammer gesteuert wird. So ist es beispielsweise möglich, beim Öffnen immer auf optimale Beleuchtung zu Schalten und beim Schließen einzelne Beleuchtungsmodule auszuschalten oder zu dimmen. So erscheint es sinnvoll, bei geschlossener Kryostatkammer nur den Probenhalter und/oder das Schneidmesser des Mikroatoms zu beleuchten.In one development of the invention, a switch is arranged on the cryostat and is electrically connected to the circuit arrangement, the switch automatically switching and / or diminishing individual and / or multiple lighting modules when opening and / or closing the cryostat chamber. With this function it is achieved that when opening the lid or the disc by an operator automatically the illumination light is controlled within the chamber. For example, it is possible to always switch to optimal lighting when opening and to switch off or dim individual lighting modules when closing them. So it makes sense, with closed cryostat chamber to illuminate only the sample holder and / or the cutting blade of the microatom.
Den LEDs des Beleuchtungsmoduls ist ein Spritzwasserschutz zugeordnet. Vorteilhaft kann das Beleuchtungsmodul mit einer Dichtung zur Kapselung der elektrischen LED Kontakte ausgestattet sein.The LEDs of the lighting module is assigned a splash guard. Advantageously, the lighting module with a seal for encapsulation be equipped with electrical LED contacts.
Die Erfindung wird anhand eines Ausführungsbeispiels mit Hilfe der schematischen Zeichnungen näher erläutert. Es zeigen:The Invention is based on an embodiment explained in more detail with the aid of the schematic drawings. Show it:
