About the Communicating Vessels Test Tubes black outline icon

Two round-bottomed test tubes with graduation marks stand side by side, capped by collars and joined both by a horizontal connecting pipe near their middle and by an arched bar overhead, with short stubs projecting left and right.

It illustrates the principle that linked containers settle to the same level, so it works in physics and hydraulics lesson slides, science course catalogs, lab equipment listings, e-learning quiz screens and engineering explainer diagrams.

This is the black outline version of the communicating vessels test tubes 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.
