Test Tube Alt

The test-tube-alt icon represents a laboratory test tube, a common piece of equipment used in chemistry and biology labs to hold and mix chemicals. The test tube is a symbol of scientific experimentation and research. It is often associated with medical testing, chemistry labs, and scientific experiments.

In software and platforms, the test tube icon is often used in applications related to science, medicine, and education. For example, it may appear in laboratory information management systems, medical research software, and educational platforms focused on science and chemistry.

From a UX perspective, the test tube icon communicates a sense of experimentation and analysis. It helps users understand that a particular feature or function is related to testing, analysis, or research. The icon can be used to represent a 'test' or 'experiment' action, making it clear to users what to expect.

Test Tube Alt is one of 615 icons in Fontisto, made by Kenan Gündoğan and released under MIT. It is drawn on a 22 × 24 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 TestTubeAltIcon to components/icons/fontisto-test-tube-alt.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 TestTubeAltIcon 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 Alt icon, or any of 615 Fontisto 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 22 × 24 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 Alt", so screen readers say what it does.

Yes. TestTubeAltIcon passes every SVG prop to the svg element, so <TestTubeAltIcon 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. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Fontisto, Kenan Gündoğan and the license.

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

Its tags are medical, science, equipment, lab, chemistry and test. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Test Tube Alt in another set.
