close-up of someone using a pipette to apply a dark pink or purple liquid to microscope slides. The slides are sitting in a metal rack or container. There are two dark glass bottles with stoppers near the left edge of the frame, along with a clear pipette and splatters of the same dark liquid. A microscope is visible to the right. Other people are visible around the table with the materials, though not directly involved with the action. One person has a notebook. The setting appears to be a laboratory or educational environment.
