The Flask Full icon shows a rounded laboratory flask with a narrow neck, broad base, and blue liquid band. Drawn in the Neon style on a 14px grid with a 1px stroke for fluid curves and clear visual hierarchy. Use it for science apps, chemistry tools, laboratory dashboards, experiments, and education interfaces. It belongs to Flex Neon set in the Flex family.

<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Neon style is especially effective in complex environments where&nbsp;quick recognition and hierarchy&nbsp;are essential. It also allows you to customize the line thickness.&nbsp;All Flex Neon icons are designed on a 14px grid with a 1px default stroke and two customizable line colors.</p>
