Illustration of an Erlenmeyer flask with two versions: an outline version on the left and a silhouette version on the right. Both images depict a classic laboratory flask shape with a conical body, flat bottom, and narrow neck. Inside each flask, there are three circular shapes representing bubbles or components of a liquid. The outline version has visible contour lines and markings, while the silhouette version is completely filled in black. This design is often used as an educational science icon.
