About the Test Tube Liquid Sample black filled icon
A single upright test tube is drawn with a thick rounded lip at the top, straight parallel walls and a U-shaped base, with a slightly tilted line across the upper third showing the surface of the liquid sample it holds. The shape communicates testing, analysis and laboratory work, and suits medical lab websites, chemistry course material, diagnostics dashboards, pharmaceutical packaging and science app menus.
Proportions are tall and narrow, roughly one part rim to five parts body, which keeps it legible even in a dense toolbar. The tilted fill line is the only interior detail, so it stays crisp when scaled down. Combine it with beaker, flask, microscope and pipette icons for a consistent laboratory set.
This is the solid black filled version of the test tube liquid sample icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
