About the Chemical Tube Bubbles black filled icon
A round-bottomed test tube with a wide flat rim holds a fill line of liquid dotted with small bubbles, and three more bubbles float above the opening. It conveys reactions, sampling, analysis and experimentation, and works well in chemistry courseware, lab management software, pharmaceutical research pages, science fair materials and school textbook diagrams.
The lip is drawn as a separate rounded bar, which keeps the tube distinct from a plain vial, and the scattered circles imply motion without extra detail. It pairs with microscope, flask and molecule icons; at 24 px, keep only the larger bubbles so the shape stays clean.
This is the solid black filled version of the chemical tube bubbles icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
