About the Chemical Test Tube black filled icon
This icon shows a tall round-bottomed test tube with a flat capped rim, four measurement graduation marks along its left wall and three small bubbles floating up from the opening. It signals experiments, reactions and sample analysis, making it a fit for laboratory software dashboards, chemistry education apps, medical testing pages, R&D pitch decks and pharmaceutical packaging.
The narrow vertical body gives the icon a distinctive tall silhouette, while the detached bubbles add movement above the rim. It pairs with flask, microscope and dropper icons from the library. Because the graduation ticks are fine, use it at 24px or larger, or swap to the filled style on dark backgrounds.
This is the solid black filled version of the chemical test tube icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
