Test Tube color filled icon

About the Test Tube color filled icon

This icon shows a test tube tilted diagonally, with a wavy line inside suggesting liquid contents, a rounded closed bottom, and a flared rim at the open end. It represents chemistry, lab testing, and scientific analysis. Use it in chemistry apps, biology course material, lab inventory tools, pharma branding, and science education content.

The diagonal tilt and curved liquid line give the tube a sense of motion and volume, distinguishing it from an upright glassware icon. It pairs with the Flask, Microscope, and Petri Dish icons in the library. Small sizes still read clearly thanks to the simple flared-rim silhouette.

This is the colour filled version of the test tube icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
