Tissue Processor
A tissue processor is described that comprises a retort for processing histological samples using various reagents, a plurality of exchangeable reagent supply containers that each comprise at least one container opening, a system of conduits, a control device for conveying reagents out of the reagent supply containers through at least one reagent conduit into the retort, and system bottles. The reagent supply containers and the system bottles are connected via the pertinent reagent conduits to at least one valve. The valve is electrically connected to the control device such that at least one of filling and emptying of the system bottles with reagents from the reagent supply containers is controlled. This design allows differently dimensioned reagent supply containers while at the same time minimizing the space requirement for the reagent containers.
1. A tissue processor comprising:
a retort for processing histological samples using various reagents;
a plurality of exchangeable reagent supply containers that each comprise at least one container opening;
a system of conduits;
a control device for conveying reagents out of the reagent supply containers through at least one reagent conduit into the retort; and
system bottles; wherein
the reagent supply containers and the system bottles are connected via the pertinent reagent conduits to at least one valve; and
the valve is electrically connected to the control device; and
conduits connect a plurality of the system bottles via the valve to at least one of the reagent supply containers, wherein each of the system bottles in the plurality of system bottles is filled with the same reagent, but distinguishes in concentration from one system bottle to another.
2. The tissue processor according to claim 1 , wherein the valve is connected via the reagent conduit to the retort such that at least one of filling and emptying of the system bottles with reagents from the reagent supply containers is accomplished via the retort.
3. The tissue processor according to claim 2 , wherein the retort is gas-tight and connected to the gas conduit, the tissue processor further comprising means for at least one of filling and emptying of the system bottles by way of a change in pressure in the retort.
4. The tissue processor according to claim 1 , further comprising a closure plug for closing the container opening, said closure plug being connected to a reagent conduit and to a gas conduit for aeration and venting of the reagent supply containers.
5. The tissue processor according to claim 4 , wherein the gas conduit is connected to a pump, and the tissue processor further comprises means for at least one of filling and emptying of the system bottles by way of a change in pressure.
6. The tissue processor according to claim 4 , wherein at least one of the reagent conduit and the gas conduit is flexible at the closure plug.
7. The tissue processor according to claim 1 , further comprising a filter device, wherein the gas conduit is connected to said filter device.
8. The tissue processor according to claim 1 , further comprising a condensate bottle, wherein the gas conduit is connected to said condensate bottle for collecting condensed reagent vapor.
9. The tissue processor according to claim 1 , wherein the valve is a rotary valve.
