- the openings 224 may also conductively connect the chambers 120, 122 to the chamber 126 of the first drum 108.
- a respective conductive connection is determined by the position of a respective opening 224 with respect to the chambers 124, 126. This position is achieved by rotating the first drum 108 relative to the second drum 106, as will be explained in more detail later.
- FIG. 2E shows a lancing device 226, which in FIG. 1 not shown.
- Lancing device 226 includes a plate 228 having one or more spikes 230 disposed adjacent to an opening 232 in plate 228, respectively.

- the protrusions 240 are configured to engage the slots 204 (as well as the protrusions 212 of the second drum 106). As long as the projections 240 are engaged with the slots 240, rotation of the first drum 108 about the longitudinal axis 104 is disabled. However, the projections 240 along with the first drum 108 are movable along the longitudinal axis 104 in the slots 204.
- the projections 240 have bevels 242, which point in the direction of the pivot point 140 during operation of the centrifuge with the cartridge 100 and are formed corresponding to the bevels 206 and 220.

- the drum 110 has projections 244 which project from the outer wall 246 of the drum 110 respectively.
- the projections 244 are adapted to engage the grooves 208 of the end 112 so that the drum 110 is displaceable in the longitudinal direction 104 in the grooves 208. A rotation of the drum 110 about the longitudinal axis 104 is thus locked.
- FIG. 3A-3E show several operating conditions during operation of the cartridge 100 FIG. 1 , wherein an additional drum 302 is shown, but this is not relevant in the present case.
- the Figures 4A-4E correspond respectively with the Figures 3A-3E and illustrate the movement of the ramps 206, 218, 220, 242 relative to each other.
- FIG. 3B shows an operating state of the cartridge 100 which is more advanced than that in FIG FIG. 4B shown condition.
- the housing 102 is shown partially transparent to reveal the interior.
- the projections 200, the slots 204, the bevels 206, the projections 212, the bevels 218, 220, the projections 240 and the bevels 242 form in conjunction with the return spring 114, the above-mentioned adjusting device 300 for defined rotation of the first drum 108 relative to the other drums 106, 110 about the longitudinal axis 104.
- FIGS. 3A and 4A show a first position in which the projections 240 of the first drum 108 engage in the slots 204 and thus a rotation of the drum 108 is locked about the longitudinal axis 104. If the rotational speed of the centrifuge is increased, then the second drum 106 pushes, by means of the bevels 220 of the contour 216, onto the bevels 242 of the first drum 108 against the action of the spring 114, compressing the spring 114. As a result, the drum 108 moves in a direction away from the pivot point 140 as indicated by the corresponding arrows in FIGS FIGS. 4A and 4B indicated. This movement is continued until the protrusions 240 disengage from the protrusions 200.
- the spring 114 presses the first drum 108 by means of the third drum 110 again in the direction of the pivot point 140.
- the second drum 106 together with their bevels 220 also back in Direction of the pivot point 140 moves, whereby the bevels 242 of the first drum 108 come to rest against the bevels 206 of the housing 102 and slide along this while performing a further rotational movement of the drum 108 in a third position, as in Figures 4D and 4E shown.
- the projections 240 of the drum 108 are again located in the slots 204 of the housing 102, so that further rotation of the drum 108 about the longitudinal axis 104 is again locked.
- the process described above may be repeated as many times as desired to rotate the first drum 108 in a defined manner relative to the other drums 106 and 110.
- the cartridge 100 further includes an electrical switch 500.
- This is partly in FIG. 5 shown schematically in a perspective view obliquely from above the first drum 108 from Figure 2F shows.
- the drum 108 is without the ramps 242 and other details Fig. 2F shown.

Furthermore, the interconnects 514 can be patterned by means of etching processes or laser ablation. Furthermore, the conductor tracks 514 can be glued or laminated directly or via a film. Furthermore, the conductor tracks 514 can also be cast during the manufacturing process of the first drum 108, for example by injection molding. The conductive traces 514 may also be coated with a protective layer. The conductor tracks 514 typically have a thickness of a few nanometers (eg 50 nm) up to a few millimeters (eg 3 mm) or can also be designed as wires. The width of the tracks 514 may vary from a few microns to a few millimeters.

Lab-on-a-Chip-Systeme bestehen typischerweise aus zwei Hauptkomponenten. Ein Testträger beinhaltet Strukturen und Mechanismen für die Umsetzung der fluidischen Grundoperationen (z.B. Mischer), welche aus passiven Komponenten, wie Kanälen, Reaktionskammern und vorgelagerten Reagenzien, oder auch aktiven Komponenten wie Ventilen oder Pumpen bestehen können. Die zweite Hauptkomponente sind Aktuations-, Detektions- und Steuereinheiten. Solche Systeme ermöglichen es, biochemische Prozesse vollautomatisiert durchzuführen.Lab-on-a-Chip systems (also referred to as the West Pocket Laboratory or the Chiplabor) accommodate all the functionality of a macroscopic laboratory on a plastic plastic-sized plastic substrate. Lab-on-a-chip systems typically consist of two major components. A test carrier includes structures and mechanisms for the implementation of basic fluidic operations (e.g., mixers), which may consist of passive components such as channels, reaction chambers and upstream reagents, or even active components such as valves or pumps.

"Komponente" meint vorliegend eine Flüssigkeit, ein Gas oder einen (oder mehrere) Partikel. Mit der "ersten und zweiten Komponente" können auch nur zwei unterschiedliche Zustände desselben Stoffs gemeint sein: Beispielsweise kann die erste Komponente als ein verklumpter Anteil und die zweite Komponente als ein flüssiger Anteil desselben Stoffs ausgebildet sein."Component" in the present case means a liquid, a gas or one or more particles. By the "first and second component", only two different states of the same substance may be meant: For example, the first component may be formed as a clumped portion and the second component as a liquid portion of the same substance.
Gemäß einer Ausgestaltung der erfindungsgemäßen Kartusche umfasst die Verstelleinrichtung eine erste Schräge, welche mit einer zweiten Schräge der ersten Trommel zusammenwirkt, um die erste Trommel aus einer ersten Stellung, in der die zweite Schräge mit einem Gehäuse der Kartusche in Drehrichtung um die Mittelachse formschlüssig in Eingriff steht, in eine zweite Stellung entlang der Mittelachse und entgegen der Wirkung eines Rückstellmittels zu verbringen, in welcher der Formschluss aufgehoben ist und sich die erste Trommel um die Mittelachse dreht. Dieser Mechanismus wird auch als "Kugelschreibermechanik" vorliegend bezeichnet.According to one embodiment of the cartridge according to the invention, the adjusting device comprises a first bevel, which cooperates with a second bevel of the first drum to the first drum from a first position in which the second bevel with a housing of the cartridge in the rotational direction about the central axis in a form-fitting engagement is to spend in a second position along the central axis and against the action of a return means in which the positive connection is released and the first drum rotates about the central axis. This mechanism is also referred to as a "ballpoint pen mechanism" herein.
Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Kartusche ist die zweite Kammer und/oder eine dritte Kammer der ersten Trommel bezogen auf die Mittelachse vor- oder nachgelagert, wobei bevorzugt die erste Kammer mittels der Verstelleinrichtung wahlweise mit der zweiten Kammer oder der dritten Kammer leitend verbindbar ist. Außerdem kann die erste Kammer bevorzugt mit unterschiedlichen weiteren Kammern - je nach Bedarf - wahlweise verbunden werden.According to a further embodiment of the cartridge according to the invention, the second chamber and / or a third chamber of the first drum with respect to the central axis upstream or downstream, wherein preferably the first chamber by means of the adjustment either with the second chamber or the third chamber is conductively connected.

Somit lässt sich ein Stapel aus beispielweise drei Trommeln bilden. Es können jedoch auch mehr als drei Trommeln vorgesehen sein.According to a further embodiment of the cartridge according to the invention, a second drum, which has the second chamber, and / or a third drum is provided, which has the third chamber, wherein preferably the second drum of the first drum relative to the center axis upstream and / or third drum of the first drum is downstream.

Dadurch lassen sich unterschiedliche Schaltkonzepte darstellen: Einmal kann die Betätigung des Schalters von der Position der Trommeln zueinander abhängen, oder die Betätigung des Schalters kann von der Position einer Trommel relativ zu dem Gehäuse abhängen.According to a further embodiment of the cartridge according to the invention, the switch comprises at least a first and a second contact element, which are contacted for the closed state of the switch and spaced apart for the open state of the switch, wherein the first contact element at an end face of the first drum and the second contact element is attached to one of the end face of the first drum facing end side of the second or third drum or the first contact element on the first, second or third drum and the second contact element on a housing of the cartridge, in particular on a projection thereof, is attached. As a result, different switching concepts can be represented: First, the operation of the switch may depend on the position of the drums to each other, or the operation of the switch may depend on the position of a drum relative to the housing.
Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Kartusche umfasst der Schalter mehrere erste Kontaktelemente, welche mittels Drehens der ersten Trommel wahlweise mit dem zweiten Kontaktelement kontaktierbar sind. Dadurch können verschiedene Schaltkreise gebildet werden. Entsprechend können in Abhängigkeit davon, welches erste Kontaktelement mit dem zweiten Kontaktelement kontaktiert ist, verschiedene elektrische Bauteile bestromt bzw. angesteuert werden.According to a further embodiment of the cartridge according to the invention, the switch comprises a plurality of first contact elements, which are selectively contactable by means of rotation of the first drum with the second contact element.

In der Kontaktstellung der ersten Trommel ist diese gegenüber der zweiten Trommel verdreht und hat sich dieser aber auch im Vergleich zur zweiten Stellung wieder an die zweite Trommel angenähert. Durch diese Annäherung werden das erste und zweite Kontaktelement kontaktiert, d.h. der Schalter geschlossen.According to a further embodiment of the cartridge according to the invention, the first and second contact element in a contact position of the first drum, which adjoins the second position of the first drum, contacted each other, preferably in the contact position, the first drum and the housing, in particular projections thereof, each other engage behind to avoid an automatic adjustment of the first drum from its contact position to a third position due to the action of the return means. In the contact position of the first drum this is rotated relative to the second drum and has this but also approximated to the second drum in comparison to the second position. By this approach, the first and second contact elements are contacted, i. the switch is closed.

Dadurch kann die Heizeinrichtung beispielsweise den notwendigen Temperaturverlauf in der ersten Kammer bereitstellen, sodass eine Polymerase-Ketten-Reaktion in einer Komponente in der ersten Kammer ablaufen kann.According to a further embodiment of the cartridge according to the invention, this has a particular in or on a housing of the cartridge, the first, second and / or third drum provided heater for particular cyclic heating of the first, second and / or third chamber, which by means of operating the electrical Switch is switchable for heating. As a result, the heating device can, for example, provide the necessary temperature profile in the first chamber so that a polymerase chain reaction can take place in a component in the first chamber.
Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Kartusche weist diese weiterhin ein insbesondere in oder an einem Gehäuse der Kartusche, der ersten, zweiten und/oder dritten Trommel vorgesehenes Halbleiterbauelement auf, welches mittels Betätigens des elektrischen Schalters ansteuerbar ist.

Es bestehen demnach verschiedene Möglichkeiten, um die erste Trommel zu drehen, welche auch in Kombination miteinander vorgesehen werden können. Die Kraft, welche die Komponenten, also beispielsweise Flüssigkeiten durch die Kartusche bewegt, kann als Zentrifugalkraft vorgesehen werden. Bei stillstehender Kartusche mit Aktor bietet sich dagegen eine Druckeinrichtung an, die einen geeigneten Druck, insbesondere Gas- oder Flüssigkeitsdruck, erzeugt, welcher die Komponenten durch die Kartusche bewegt.According to a further embodiment of the cartridge according to the invention, this is designed for insertion into a centrifuge and centrifuging thereof and the adjusting device is arranged to actuate the first drum for rotation about the central axis when the centrifugal force exceeds a predetermined threshold value and / or Adjusting an actuator, which actuates the first drum for rotating about the central axis directly or indirectly.

Wird die Drehzahl nun wieder reduziert, was mit einer entsprechenden Reduzierung der Zentrifugalkraft einhergeht, so drückt die Feder 114 die erste Trommel 108 mittels der dritten Trommel 110 wieder in Richtung des Drehpunkts 140. Dadurch wird die zweite Trommel 106 samt ihrer Schrägen 220 ebenfalls wieder in Richtung des Drehpunkts 140 bewegt, wodurch die Schrägen 242 der ersten Trommel 108 gegen die Schrägen 206 des Gehäuses 102 zum Liegen kommen und entlang dieser unter Ausführung einer weiteren Drehbewegung der Trommel 108 in eine dritte Stellung gleiten, wie in den

Die Leiterbahnen 514 sind auf die Oberfläche der Trommelwand 518 zumindest abschnittsweise beispielweise mittels Aufdampfens, Galvanisierens, Plasmabeschichtens oder Druckens aufgebracht. Weiterhin können die Leiterbahnen 514 über Ätzprozesse oder Laserablation strukturiert werden. Des Weiteren können die Leiterbahnen 514 direkt oder über eine Folie aufgeklebt oder laminiert werden. Ferner können die Leiterbahnen 514 auch während des Fertigungsprozesses der ersten Trommel 108 beispielweise im Spritzgussverfahren mit eingegossen werden. Die Leiterbahnen 514 können auch mit einer Schutzschicht überzogen sein. Die Leiterbahnen 514 weisen typischerweise eine Dicke von wenigen Nanometer (z.B. 50 nm) bis hin zu einigen Millimeter (z.B. 3 mm) auf oder können auch als Drähte ausgelegt werden. Die Breite der Leiterbahnen 514 kann von wenigen Mikrometern bis zu einigen Millimetern variieren. Die Leiterbahnen 514 können metallische Materialien wie Kupfer, Gold, Aluminium, Platin, Titan deren Legierungen oder dotierte Halbleitermaterialien wie Silizium aufweisen.The conductor tracks 514 are applied to the surface of the
Das zweite Kontaktelement 530 ist an der Stirnseite (entspricht der Unterseite 222, siehe
Wird nun die erste Trommel 108 mittels der Verstelleinrichtung 300 verstellt ("Betätigung der Kugelschreibermechanik"), weist das erste Kontaktelement 512 bzw. die erste Trommel 108 anfänglich noch einen Abstand 532 in Bezug auf das zweite Kontaktelement 530 bzw. die zweite Trommel 106 auf. Dies entspricht der ersten Stellung der ersten Trommel 108, siehe
Anstelle der Heizeinrichtung 534 könnte auch ein beliebig anderes elektrisches Bauteil mittels des Schalters 500 geschaltet werden. Insbesondere kommen hier metallische Bauelemente (in Multilayerstruktur und oder in Form von Legierungen) und/oder Halbleiterelemente, beispielsweise CMOS, Elektroden oder Sensoren, beispielsweise ChemFETs, in Frage. Diese können in den Trommeln 106, 108, 110 oder in dem Gehäuse 102 angeordnet sein. Die vorstehenden Ausführungen zu den Leiterbahnen 514 gelten entsprechend. So können Elektroden beispielsweise mittels Aufdampfens auf der ersten Trommel 108 erzeugt werden.Instead of the
Beispielweise kann der Schalter mit einer Ausleseeinrichtung 538 in Form eines Mikrochips (Halbleiterelement) 538 verbunden sein. Die Ausleseeinrichtung 538 registriert, zu welchen Zeitpunkten der Schalter 500 geschlossen wird. Die Ausleseeinrichtung 538 kann den entsprechenden Schaltverlauf abspeichern. Der Schaltverlauf kann wiederum beispielweise zu Qualitätssicherungszwecken aus der Ausleseinrichtung 538 insbesondere drahtlos ausgelesen werden.For example, the switch may be connected to a
Mittels der Verstelleinrichtung, d.h. mittels geeigneter Steuerung der Drehzahl der Zentrifuge, gelangen die Trommeln 106, 108 bzw. die Kontaktelemente 512, 530 aus der Kontaktstellung in die vorstehend erwähnte dritte Stellung, siehe
Wird die Drehzahl nun wieder erhöht wiederholt sich der vorstehende Prozess, jedoch mit dem Unterschied, dass diesmal das andere erste Kontaktelement 510 mit dem zweiten Kontaktelement 530 kontaktiert wird, siehe
Es könnten auch mehrere zweite Kontaktelemente 530 vorgesehen sein.It could also be provided a plurality of
Das erste Kontaktelement 510 ist an einer Stirnseite der ersten Trommel 108 vorgesehen, welche von dem Drehpunkt 140 weg weist. Das zweite Kontaktelement 530 ist an einem Vorsprung 700 angebracht, welcher sich von dem Gehäuse 102 erstreckt. Das zweite Kontaktelement 530 weist in Richtung des Drehpunkts 140.The
Die erste Trommel 108 umfasst eine Nase 800, welche sich von der Trommelwand 518 radial in Bezug auf die Mittelachse 104 nach außen erstreckt. Das erste Kontaktelement 510 ist auf der Nase 800 angeordnet und weist in Richtung des Drehpunkts 140. Das zweite Kontaktelement 530 ist an einer Nase 700 des Gehäuses 102 vorgesehen und weist in einer Richtung weg von dem Drehpunkt 140.The
Mittels der Verstelleinrichtung 300 werden die Kontaktelemente 510, 530 miteinander in Kontakt gebracht, wobei die erste Trommel 108 entlang der Längsachse 104 in einer Richtung weg von dem Drehpunkt 140 bewegt und hiernach gedreht wird, siehe
Der Aktor 900, die Vorsprünge 200, die Schlitze 204, die Schrägen 206, die Vorsprünge 212, die Schrägen 218, 220, die Vorsprünge 240 sowie die Schrägen 242 bilden im Zusammenspiel mit der Rückstellfeder 114 bei diesem Ausführungsbeispiel die vorstehend erwähnte Verstelleinrichtung 300 zum definierten Verdrehen der ersten Trommel 108 gegenüber den anderen Trommeln 106, 110 um die Längsachse 104.The
Drückt der Aktor 900 mittelbar oder unmittelbar, beispielweise mit seiner Stirnseite 902, auf die zweite Trommel 106, so drückt die Trommel 106 wiederum mittels der Schrägen 220 der Kontur 216, s.
Gibt der Aktor 900 nunmehr die zweite Trommel 106 frei, so drückt die Feder 114 die erste Trommel 108 mittels der dritten Trommel 110 wieder in Richtung des Drehpunkts 140. Dadurch wird die zweite Trommel 106 samt ihrer Schrägen 220 ebenfalls wieder in Richtung des Drehpunkts 140 bewegt, wodurch die Schrägen 242 der ersten Trommel 108 gegen die Schrägen 206 des Gehäuses 102 zum Liegen kommen und entlang dieser unter Ausführung einer weiteren Drehbewegung der ersten Trommel 108 in die dritte Stellung gleiten, wie in den
Weiter alternativ könnte anstelle des Rückstellmittels 114 auch ein weiterer nicht dargestellter Aktor verwendet werden.Further alternatively, instead of the return means 114, another actuator, not shown, could be used.
Grundsätzlich kann der Aktor 900 elektrisch-, mechanisch- und/oder druckbetrieben sein. Insbesondere bietet sich ein piezoelektrisch-, elektrostatisch-, semi-mechanisch-manuell oder elektromagnetischbetriebener Aktor 900 an. "betrieben" meint hier das Wirkprinzip, welches der Aktor 900 ausnutzt, um die Betätigungskraft zum Betätigen der Trommel 106 (oder je nach Ausführungsform auch eine der Trommeln 108 oder 110) zu erzeugen. Beispielweise kann der Aktor 900 einen Elektromagneten aufweisen, welcher mit einem in einer der Trommeln 106, 108, 110 angeordneten Metallteil zusammenwirkt, das der Elektromagnet mittels geeigneter Ansteuerung desselben anzieht oder abstößt, um dadurch die die oben erläuterte Verstellung der Trommeln 106, 108, 110 zueinander zu erreichen. Die auf die zweite Trommel 106 mittels des Aktors 900 aufgebrachte Druckkraft beträgt typischerweise 0,5-100 N. Die von dem Aktor aufzubringende Druckkraft reduziert sich entsprechend der wirkenden Zentrifugalkraft.In principle, the
Bevorzugt ist eine geeignete, nicht dargestellte Steuereinrichtung vorgesehen, welche den Aktor 900 ansteuert, sodass die Trommeln 106, 108, 110 zu der gewünschten Zeit die jeweils gewünschte Position zueinander einnehmen. Dazu kann die Steuereinrichtung einen Timer und/oder einen integrierten Schaltkreis aufweisen.Preferably, a suitable, not shown, control device is provided, which controls the
Gemäß einem nicht dargestellten Ausführungsbeispiel sind lediglich die erste Trommel 108 und die zweite Trommel 106 vorgesehen. Ein Stellglied in Form einer Welle ist einerseits mit dem Aktor 900 und andererseits mit der ersten Trommel 108 verbunden ist. Der Aktor 900, insbesondere ein Elektromotor, dreht dabei die Welle und dadurch die erste Trommel 108 um die Mittelachse 104, wodurch unterschiedlichen Kammern 120, 122, 124 miteinander leitend verbunden werden, wie vorstehend beschrieben. Eine Kugelschreibemechanik ist bei diesem Ausführungsbeispiel nicht vorgesehen. Der Aktor 900 kann ferner dazu eingerichtet sein, die Welle auch entlang der Mittellinie 104 zu bewegen, um dadurch die erste Trommel 108 von der zweiten Trommel 106 für das Drehen zu beanstanden und nach dem Drehen die Trommeln 106, 108 wieder aneinander zu pressen, wodurch eine dichte, leitende Verbindung beispielweise zwischen der Kammer 120 und der Kammer 124 vorgesehen und/oder der Schalter 500 geschlossen wird.According to an embodiment not shown, only the
Die Zentrifuge 1000 weist Spulen 1002 auf, welche beispielsweise in einen Deckel und/oder Boden der Zentrifuge integriert sein können. Mittels der Spulen 1002 wird der Strom, beispielweise zum Betreiben der Heizeinrichtung 534, in die Kartusche 100 eingekoppelt. Dazu weist die Kartusche 100 eine oder mehrere nicht dargestellte Spulen auf. Die Kartusche 100 ist in einen Rotor 1004 der Zentrifuge 1000 eingesetzt.The
Anstelle der Spulen 1002 könnte auch eine Batterie verwendet werden, welche in der Kartusche 100 angeordnet ist und beispielsweise die Heizeinrichtung 534 mit Energie versorgt.Instead of the
Die Energieversorgung kann als wieder verwendbares Bauteil oder Gerät ausgelegt werden, welches im Betrieb der Kartusche 100 Bestandteil dieser ist. Z.

Ein Sensor in dem Gehäuse 102 der Kartusche 100 kann so ausgelegt werden, dass dieser nach Durchführung der biochemischen Prozesse aus dem Gehäuse 102 herausgenommen und die Sensordaten dann extern ausgelesen werden können.A sensor in the
Für eine Kartusche 100 mit Komponenten 536 in dieser, welche druckgetrieben und nicht zentrifugal prozessiert werden, kann die Energieversorgung und die Ansteuerung von Sensoren über herkömmliche Kontaktierungen erfolgen.For a
Gemäß einer weiteren Ausgestaltung können Messsignale der Sensoren oder Kartusche 100 über eine Sendeeinrichtung (z.B. mittels eines RFID-Chips) nach außerhalb der Kartusche 100 weitergeleitet werden. Dies ermöglicht die Durchführung von Echtzeitmessungen (Real-Time). In einer noch weiteren Ausführungsform kann die Zentrifuge 1000 mittels eines RFID-Chips in der Kartusche 100 erkennen, welcher Kartuschentyp eingelegt wurde und somit automatisch das korrekte Prozessierungsprotokoll (z.B. Frequenzprotokoll mit Beschleunigungs- und Abbremsrampen, Zielfrequenzen und Haltezeiten) verwenden.In accordance with a further embodiment, measurement signals of the sensors or
Je nach Ausführungsform können die zweite Trommel 106 und/oder die dritte Trommel 110 ortsfest oder beweglich in Bezug auf das Gehäuse 102 vorgesehen sein. Die Trommeln 106, 110 können beispielweise jeweils mittels eines weiteren Aktors drehbar um die Mittelachse 104 vorgesehen sein.Depending on the embodiment, the
Die Leiterbahnen 514 können z.B. im Gehäuse 102 verlaufen und direkt mit Sensoren kontaktiert werden, welche in nicht-drehbaren Trommeln (beispielweise die zweite Trommel 106) vorgesehen sind. Somit ist eine einfache Integration von elektrischen Systemen ermöglicht.The
Der Schalter 500 kann grundsätzlich insbesondere zwischen zwei beliebigen Trommeln 106, 108, 110 oder einer beliebigen Trommel 106, 108, 110 und dem Gehäuse 102 gebildet sein.The
Weiterhin kann die Mischkammer 124 eine nicht dargestellte Hindernisstruktur, beispielsweise ein Sieb oder eine Gitterstruktur, aufweisen, welche dazu eingerichtet ist, unter Einwirkung einer Zentrifugalkraft (wenn also die Drehzahl der Zentrifuge einen vorbestimmten Schwellwert überschreitet) sich durch die Komponente 536 zu bewegen, um diese dadurch zu vermischen.Further, the mixing
Das Gehäuse 102 und die Trommeln 106, 108, 110 können aus demselben oder unterschiedlichen Polymeren hergestellt sein. Bei dem einen oder mehreren Polymeren handelt es sich insbesondere um Thermoplaste, Elastomere oder thermoplastische Elastomere. Beispiele sind Cyclo-olefin Polymer (COP), Cyclo-olefin Copolymer (COC), Polycarbonate (PC), Polyamide (PA), Polyurethane (PU), Polypropylen (PP), Polyethylene terephthalate (PET) oder Poly(methyl methacrylate) (PMMA).The
Die zweite Trommel 106 und/oder die dritte Trommel 110 können einstückig mit dem Gehäuse 102 gebildet sein.The
