About the Test Tube Liquid Sample black outline 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 black outline version of the test tube liquid sample icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
