Test Tube 2

The test-tube-2 icon represents another type of test tube, a laboratory equipment used for scientific experiments and research.

The icon can be used in various science-related software, platforms, or tools, such as laboratory management systems, scientific publishing platforms, or educational websites.

From a UX perspective, the icon communicates a sense of analysis and investigation, helping users understand the functionality of a button or link related to scientific research.

Test Tube 2 is one of 799 icons in SmartIcons Glyph, made by SmartIcons and released under CC BY SA 4.0. It is drawn on a 17 × 16 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 TestTube2Icon to components/icons/si-glyph-test-tube-2.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 TestTube2Icon 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 Test Tube 2 icon, or any of 799 SmartIcons Glyph 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 17 × 16 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

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="Test Tube 2", so screen readers say what it does.

Yes. TestTube2Icon passes every SVG prop to the svg element, so <TestTube2Icon 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.
