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 4 and hexagon carbon share its geometry, so mixed layouts stay coherent. Preview it free below — copying the SVG or downloading the file takes any Majesticons license.
