Test tube filled 2 icon

The test tube filled 2 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.

Designers often combine it with the nearby hexagon 4 and hexagon carbon icons. Every style previews free, and a single lifetime license covers copy and download across all 11,000+ icons.
