Test Tube Light

The test-tube-light icon represents a light or outlined laboratory test tube, often used to convey a sense of simplicity or minimalism. It symbolizes a container used to hold and mix chemicals, biological samples, or other substances.

In real-world applications, this icon appears in software and platforms related to scientific research, medical testing, and educational materials. It's often used in laboratory information management systems, electronic lab notebooks, and science education software.

From a UX perspective, the test-tube-light icon communicates a sense of ease, simplicity, or clarity related to scientific testing or research. It helps users understand that they are interacting with a straightforward or intuitive feature or tool.

Test Tube Light is one of 9,161 icons in Phosphor, made by Phosphor Icons and released under MIT. It is drawn on a 256 × 256 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 TestTubeLightIcon to components/icons/ph-test-tube-light.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 TestTubeLightIcon 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.

Yes, if your project has @phosphor-icons/react: Test Tube Light is `TestTube` there, used as <TestTube weight="light" />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.

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 Light icon, or any of 9,161 Phosphor 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 256 × 256 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 Light", so screen readers say what it does.

Yes. TestTubeLightIcon passes every SVG prop to the svg element, so <TestTubeLightIcon 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 Phosphor, Phosphor Icons and the license.

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