A device for mitigating evaporation of treatment liquids from a sample on a substrate can include a solvent reservoir and a conduit. A slide with a sample on a surface thereof can be placed into a device, creating a capillary gap between the slide surface and a surface of the device. Treatment fluids can be dispensed and drawn into the capillary gap, such as by capillary action. The slide and/or the reservoir can be moved towards the conduit, such that the fluid in the capillary gap contacts a fluid meniscus formed in the conduit. In this manner, fluid lost to evaporation from the capillary gap can be replenished by fluid in the conduit and reservoir, via capillary action. The slide and/or reservoir can then be moved again to break contact with the conduit, and the fluid within the capillary gap can then be mixed, such as by rocking the slide. |
