Flask icon

Flask is one of the science icons in Majesticons, drawn by hand on the library's consistent 24×24 grid. All 3 styles (line, duotone and solid) stay visually consistent, so it slots cleanly into lab tools, research apps and education sites.

Designers often combine it with the nearby carbon cell and cell icons. It is part of the free MIT-licensed set: copy or download the line and solid versions below, no license needed.
