Slide-staining machine. Automated carousel-style machine for staining microscope slides in a histology laboratory. Slides containing biological preparations, such as tissue sections, are placed face down in holding devices on the underside of the circular platform at top. The slides are sequentially dipped into different types of stain in the white containers as the machine rotates. The different solutions stain different features on the slide. For example, haematoxylin stains cell nuclei blue/black, whereas eosin stains cell cytoplasm and connective tissue fibres pink, orange and red.
