About the Chemical Test black outline icon
A tall test tube stands upright with a rounded bottom, a thick collar at the mouth and a column of measuring marks running down its inner wall, while six small bubbles of different sizes float above it. Together they suggest an active reaction, sampling and analysis, fitting laboratory dashboards, chemistry lesson slides, pharmaceutical sites, water testing services and research report covers.
The tube is narrow and takes up the full height of the frame, so the graduation ticks alternate in length to keep the silhouette from looking striped. Pair it with flask, microscope and beaker icons. At small sizes, use the version without bubbles for a cleaner edge.
This is the black outline version of the chemical test 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.
