Test tube off icon

The test tube off icon belongs to the science set of Majesticons and shares the library's hand-crafted 24×24 grid geometry. It comes in line, duotone and solid styles, a natural fit for lab tools, research apps and education sites. Because the line variant uses real strokes, its weight adjusts cleanly at any size.

Related glyphs like hexagon 4 and hexagon carbon share its geometry, so mixed layouts stay coherent. Every style previews free, and a single lifetime license covers copy and download across all 11,000+ icons.
