Circle Flask

The circle-flask icon represents a flask embedded in a circle, symbolizing science and experimentation. It originates from laboratory equipment and is widely used in scientific and educational contexts.

In real-world applications, this icon appears in science and education apps, laboratory software, and educational resources. It's often used to represent scientific or experimental functionality.

From a UX perspective, the circle-flask icon communicates a sense of science, experimentation, and discovery. It helps users understand that an action or feature is related to scientific inquiry or experimentation.

Circle Flask is one of 3,933 icons in Streamline, made by Streamline and released under CC BY 4.0. It is drawn on a 14 × 14 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds CircleFlaskIcon to components/icons/streamline-circle-flask.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed CircleFlaskIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Circle Flask icon, or any of 3,933 Streamline icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 14 × 14 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Circle Flask", so screen readers say what it does.

Yes. CircleFlaskIcon passes every SVG prop to the svg element, so <CircleFlaskIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with credit: CC BY 4.0 asks you to credit the author (Streamline) where you use the icons. The full terms are in the license, linked on this page.

Yes. CC BY 4.0 asks you to credit the author where you use the icons, for example "Icons by Streamline, CC BY 4.0" on an about or credits page.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are UI, education, science, streamline, laboratory and experimentation. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Circle Flask in another set.

Streamline draws many icons in several styles: Solid next to the default. Open the library and pick a style above the grid to see Circle Flask's siblings in it.
