A method and an apparatus are described for infiltrating tissue samples with carrier material, preferably paraffin. A supply of carrier material is kept ready for use in a supply station. From there, the carrier material can be delivered into at least a first and a second container. In these first and second containers carrier materials of differing degrees of purity are kept ready for use, respectively, for performing various infiltration steps on tissue samples. By means of the described method and apparatus the tissue processor can be operated with as little interruptions as possible and an ease in operation is achieved.

Method and apparatus for infiltrating tissue samples with paraffin

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.

Tissue Processor

A method for controlling a tissue processor and a tissue processor for processing tissue samples is described. A retort is provided including a cover that can be opened and closed by an operator. The retort cover is closed prior to tissue processing. The actuation state of a first and a second operating element can be determined. An operator is prompted to confirm unlocking of the closed retort cover by actuating a second operating element. The tissue processing is interrupted when an actuation of the second operating element is determined and the closed retort cover is unlocked and is continued after the retort cover is once again locked. After having completed tissue processing the retort cover is unlocked. By means of the described method and tissue processor improper intervention during ongoing tissue processing is prevented.

Method for controlling a tissue processor and tissue processor

A tissue processor () is described, having a retort () for processing histological samples with different reagents, having multiple reagent reservoir vessels (), and having a conduit system and a control device () for delivering reagents out of the reagent reservoir vessels () into the retort (). A suction conduit () projects into each reagent reservoir vessel () through the vessel opening () for reagent withdrawal. A closure system () having an externally tapered and internally hollow closure plug () is provided for closing off the vessel opening (). The suction conduit () is guided through a cavity () of the closure plug () for reagent withdrawal.
