Test Tube

The test tube icon represents a laboratory vessel used for holding and mixing chemical substances. Test tubes are commonly used in scientific research, medical testing, and educational settings. They are an essential tool for scientists and researchers.

Test tube icons like this are often used in science-related applications, such as educational websites, laboratory software, and medical apps. They can also be used to represent a 'science' or 'research' theme in design projects.

From a UX perspective, the test tube icon communicates a sense of experimentation, discovery, and analysis. It can be used to draw attention to a call-to-action or to add a touch of personality to a design.

Test Tube is one of 3,800 icons in Noto Emoji, made by Google Inc and released under Apache 2.0. It is drawn on a 128 × 128 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 TestTubeIcon to components/icons/noto-test-tube.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 TestTubeIcon 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 icon, or any of 3,800 Noto Emoji icons, and install it from a prompt.

It's multicolor, so it keeps its own colors.

Set width and height on the component, or a class like size-6. It's drawn on a 128 × 128 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It keeps its own colors in light and dark mode, so check it against both backgrounds. 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", so screen readers say what it does.

Yes. TestTubeIcon passes every SVG prop to the svg element, so <TestTubeIcon 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. Apache 2.0 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: Apache 2.0 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 Noto Emoji, Google Inc and the license.

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