Test tube filled icon

The test tube filled icon is part of the science collection in Majesticons, hand-crafted like every icon in the library on a shared 24×24 grid. Pick between line, duotone and solid depending on the visual weight your design needs; typical homes include lab tools, research apps and education sites.

Related glyphs like hexagon close and hexagon drop share its geometry, so mixed layouts stay coherent. It is part of the free MIT-licensed set: copy or download the line and solid versions below, no license needed.
