Test Tube Diagonal

The test-tube-diagonal icon represents active laboratory experiments and ongoing chemical processes in scientific applications. Featuring a tilted test tube suggesting mixing or reaction in progress, this symbol indicates active experiments, running tests, and the dynamic laboratory operations essential for scientific research platforms and quality assurance workflows.

In laboratory information management systems like LabWare and scientific workflow platforms such as Benchling, diagonal test tube representations appear for experiments in progress or active sample processing. Quality control dashboards including pharmaceutical manufacturing systems display it for ongoing batch testing, while educational science platforms like PhET Interactive Simulations use it for active demonstration modes and interactive chemistry experiments.

From a laboratory workflow perspective, the diagonal orientation communicates more than static testing—it represents chemical reactions in progress, the active manipulation phase that distinguishes hands-on experimentation from prepared samples, and the dynamic processes where scientists actively engage with materials rather than simply observing stored specimens.

Test Tube Diagonal is one of 1,655 icons in Lucide, made by Lucide Contributors and released under ISC. It is drawn on a 24 × 24 grid with a 2 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds TestTubeDiagonalIcon to components/icons/lucide-test-tube-diagonal.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 TestTubeDiagonalIcon 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 lucide-react: Test Tube Diagonal is `TestTubeDiagonalIcon` there, used as <TestTubeDiagonalIcon />. 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 Diagonal icon, or any of 1,655 Lucide 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 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Test Tube Diagonal is a line icon drawn with a stroke width of 2. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

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 Diagonal", so screen readers say what it does.

Yes. TestTubeDiagonalIcon passes every SVG prop to the svg element, so <TestTubeDiagonalIcon 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. ISC 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: ISC 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 Lucide, Lucide Contributors and the license.

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

Its tags are science, process, chemistry, experiment, active and laboratory. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Test Tube Diagonal in another set.
