Method and system for use of treatment liquids in an apparatus for staining of tissue specimens on microscope slides
A method and a system for use of treatment liquids in an apparatus for staining of tissue specimens on microscope slides, wherein the apparatus comprises a plurality of vessels ( 4 ) for receiving different liquids for treatment of the tissue specimens, a plurality of tanks ( 11 ) for treatment liquids, connecting lines ( 15 ) between the tanks and the vessels, a plurality of pumps ( 13 ) connected on the connecting lines, and a control unit for control of the apparatus and the liquid treatment by means of a data program, wherein the control unit is arranged for selective control of the relevant pumps ( 13 ), so that vessels ( 4 ) to be used in a staining process, are filled with liquid ( 14 ) at the start of the staining process, and so that the liquid-filled vessels ( 4 ) are emptied automatically when they are no longer to be used in the staining process.
1. A method for using liquids in an apparatus for staining of tissue specimens on microscope slides,
wherein the apparatus comprises at least one vessel wherein the at least one vessel is connected to a supply line comprising a first filter, wherein the supply line connects the at least one vessel to at least one tank carrying liquid for staining the tissue specimen via the first filter;
creating a circulatory system by automatically pumping the liquid for staining the tissue specimen from the at least one tank to the at least one vessel at the start of the staining process and automatically removing the liquid for staining the tissue specimen from the at least one vessel to at least one waste tank through a return line;
wherein the liquid is removed at a time defined by a data program.
2. The method of claim 1 , further comprising creating a through-flow system through the at least one vessel by pumping liquid continuously into the vessel and draining liquid continuously from the vessel.
3. The method of claim 1 , wherein the at least one tank and the at least one waste tank are the same tanks.
4. The method of claim 1 , wherein the at least one vessel comprises the microscope slide.
5. The method of claim 1 , wherein the at least one vessel is a reagent station.
6. The method of claim 1 , wherein the liquid for staining the tissue specimen is removed from the at least one vessel by draining.
7. The method of claim 1 , wherein the liquid for staining the tissue specimen passes through a second filter before reaching the at least one waste tank.
8. The method of claim 1 , where the at least one tank has a dedicated pump.
9. The method of claim 1 , wherein the liquids are supplied to the at least one vessel though at least one inlet opening in the bottom of the vessel, and are removed via at least one second outlet opening in the bottom of the vessel.
