Flask black outline icon

About the Flask black outline icon

This icon shows a conical Erlenmeyer flask with graduation tick marks along its neck and a wavy liquid line near the base. It works for chemistry lab interfaces, science education materials, pharmaceutical and biotech branding, and laboratory inventory or catalog listings.

Its tapered triangular body and marked neck set it apart from the round-bottom flask elsewhere in the set, giving designers a distinct flask shape to pair with beaker and test tube icons. The graduation marks stay legible even at smaller display sizes.

This is the black outline version of the flask icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
