About the Round Bottom Flask black filled icon
A round-bottom laboratory flask shows a wide spherical base, a narrow graduated neck marked with measurement ticks, and a stopper capping the opening. It signals chemistry, experiments and scientific research, and suits science education apps, lab-inventory systems, pharmaceutical dashboards, presentation slides and biotech product pages.
The wide sphere balances the slim neck, and the tick marks and stopper add authentic lab detail without clutter. It pairs well with test-tube and microscope icons; because the round base is the widest part, give the icon enough vertical space so it doesn't look cramped.
This is the solid black filled version of the round bottom flask icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
