About the Test Tube Circle Badge black outline icon
A test tube tilted to the right inside a thin circular frame, with a flared rim at the top, a rounded base, short graduation marks along one side and a straight line marking the liquid level. It reads as lab testing, sample collection, diagnostics and research. Use it on medical lab result pages, blood test booking flows, chemistry course materials, healthcare app menus and science presentation slides.
The tube runs on a diagonal so it spans the circle fully, while the small tick marks give it measurable, clinical detail rather than a plain tube shape. It sits beside microscope, flask and blood drop icons in the library. Use 32 px or larger so the graduation marks remain distinct.
This is the black outline version of the test tube circle badge icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
