Abstract

The present invention provides a method and apparatus for processing samples on a slide. [Solution] The capillary processing module has a crank for raising and lowering a slide, or a side inlet for applying fluid to the slide, or both. When the crank lowers the slide, a capillary gap is formed between the slide and the chamber floor of the capillary processing module. Due to capillary action, the fluid spreads through the capillary space across the processing area and comes into contact with the sample. When the crank raises the slide, the capillary gap disappears, and the fluid is drawn out of the processing area of ​​the slide.
