Staining reagents and other liquids for histological processing of biological specimens and associated technology

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. 在自动化组织染色系统中处理标本包括使载片载体机器人式地运动到系统的染色器内，载片载体承载分别承载标本的载片，且标本至少部分嵌在石蜡中。根据用于至少脱蜡、染色和对比染色标本的预定方案将液体自动地分配到载片上。在自动地分配液体之后，能够使载片载体机器人式地从染色器运动出来。在些实施例中，在使载片载体运动到染色器内之后且在使载片载体从染色器运动出来之前，分配到载片上的全部液体的总体具有比元醇的体积浓度更大的多元醇体积浓度。
