The Flask Empty icon shows a simple laboratory flask with a narrow neck, rounded rim, and broad base. Drawn in the gradient style on a 14px grid, its filled silhouette stays clear and impactful. Use it for chemistry tools, laboratory apps, experiment screens, science education, and research dashboards. It belongs to Core Gradient set in the Core family.

<p>Core is timeless, like the Helvetica font or The Beatles. With its minimalist design and neutrality, it can adapt to any layout.&nbsp;The Gradient style is best suited for designs where impact and immersion are key, especially on dark backgrounds. All Core Gradient icons are designed on a 14px grid using filled shapes as gradient colors.</p>

Core Gradient

<p>The Helvetica of icons. Core is stripped to essential form with generous spacing. It's a timeless workhorse for interface design.</p>

Flask Empty is a gradient-style Icon from Core Gradient set.
