Devices and methods for the deposition of reagents onto cells or tissue samples are disclosed. Also disclosed are reagent compositions suitable for dispensing via a droplet-on-demand system.

Inkjet deposition of reagents for histological samples

Processing specimens in an automated histological staining system comprising robotically moving a slide carrier into a stainer of the system, the slide carrier carrying slides which respectively carry the specimens, and the specimens being at least partially embedded in paraffin. Liquids are automatically dispensed onto the slides according to a predetermined recipe for at least deparaffinizing, staining, and counterstaining the specimens. The slide carrier can be robotically moved out of the stainer after automatically dispensing the liquids. In some embodiments, a total of all liquid dispensed onto the slides after moving the slide carrier into the stainer and before moving the slide carrier out of the stainer has a greater volumetric concentration of polyol than of monohydric alcohol.
