About the Chemical Tube Circle Badge black outline icon
A round-bottomed test tube with a wide flat cap stands inside a thin circle, its lower half marked with short measurement ticks along one side. It represents lab testing, chemical analysis and scientific research. Use it on laboratory service pages, chemistry lessons, medical diagnostic apps, pharmaceutical product sheets and science project graphics.
The stopper sits noticeably wider than the tube body, and the graduation marks give the empty vessel scale. It pairs with flask, microscope and dropper marks in the same lab set. Drop the circle below 24 px so the ticks remain visible.
This is the black outline version of the chemical tube circle badge 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.
