About the Graduated Test Tube Liquid black outline icon
A tall round-bottomed test tube stands upright with a thickened lip at the top, four short graduation marks along the upper left edge and a wavy line across the middle marking the liquid surface, leaving the lower half filled. It suits chemistry course materials, laboratory service sites, medical testing and diagnostics apps, pharmaceutical product pages and science infographics.
The narrow vertical body leaves generous white space either side, so the tick marks and the curved fluid line become the only detail and stay easy to read. It pairs with flask, microscope, pipette and beaker icons in the same laboratory set. In dense toolbars, pair it with a label, since a lone slim tube can be mistaken for a thermometer.
This is the black outline version of the graduated test tube liquid icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
