About the Graduated Test Tube black outline icon
A single tall tube stands upright with a rounded bottom, a flat stopper across the top and a ladder of measurement marks running up the left side. Nothing is poured inside, so it reads as clean glassware waiting for a sample. Fits laboratory websites, chemistry lessons, medical test flows, pharmaceutical packaging and research report slides.
The graduation ticks alternate long and short, adding texture without clutter, while the stopper's width anchors the narrow body. Group it with flask, microscope and pipette icons for a lab set. At small sizes switch to the fill style so the marks do not blur.
This is the black outline version of the graduated test tube icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
