About the Cracked Test Tube black filled icon
Shows a cylindrical test tube with a rounded bottom, a flat rim at the top, bubbles floating above the opening, tick marks along one edge, and a jagged crack splitting the tube in half. It represents chemistry, lab experiments and breakage or hazard warnings, and suits science education apps, lab-safety guides, chemistry games and pharma content.
Liquid fills the lower half below the crack line while the upper half stays empty, and three small circles denote rising bubbles or vapor. It pairs with beaker, microscope and flask icons in the library; the crack detail reads best at 48px or larger.
This is the solid black filled version of the cracked test tube icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
