HEMATOXYLIN PRECIPITATE CLEANING METHOD AND SYSTEM

摘要

A process for removing hematoxylin precipitate from a surface of an automated hematoxylin stainer, systems adapted for performing such processes. The process and systems use a hematein precipitate removal solution having a pH in the range of between about 8.9 and 10.5 and including a liquid oxidizing component and alkaline component.;The hematein precipitate removal solution is placed in contact with a surface of the automated hematoxylin stainer, thereby dissolving any hematein precipitate deposited thereon.

主权项

1. A method of removing hematein precipitate from an automated hematoxylin staining system comprising:
providing a liquid oxidizing component comprising a peroxide and water and an alkaline component, wherein the liquid oxidizing component and the alkaline component are separate; combining the liquid oxidizing component and alkaline component in a container to form a hematein precipitate removal solution having a pH in the range of between about 8.9 and 10.5; placing the container of the hematein precipitate removal solution in a position to enable one or more hematoxylin dispensing component(s) of the automated hematoxylin staining system to receive and move the solution through an interior surface of the one or more hematoxylin dispensing component(s); activating the automated staining system to move the hematein precipitate removal solution into the interior surface of the hematoxylin dispensing component(s); contacting said interior surface for at least 30 minutes.
