Description

[0002] With the development of society and advancements in science and technology, biotechnology research is becoming increasingly prominent in the natural sciences and national science and technology. As an essential tool for basic research, biological tissue stainers will be widely used in hospitals, research institutions, and medical schools for histological and cytological analysis, diagnosis, and research. Currently, cold and hot staining equipment are the main methods used for biological tissue staining. Compared to cold staining equipment, hot staining equipment can accelerate the reaction of the dye with cellular components, thereby shortening the entire staining process. Heat treatment can also increase the permeability of cell walls and cell membranes, allowing the dye to more easily penetrate the cell interior, thereby improving the staining effect. Heat treatment also helps to fix the cell morphology, preventing deformation and damage to the cell structure during the staining process. Certain staining techniques with specialized requirements, such as certain immunohistochemical stains, require heat treatment to enhance the staining effect. However, with current hot staining equipment, the temperature of the dye solution changes upon contact with the slide, affecting the staining effect. Utility Model Content
