Science Icon Set

Last Updated on August 24, 2026 by Editorial Team

A nice set of science icons designed and shared by Ümit Can Evleksiz.

Features:

• the set includes three categories of icons: chemistry, physics, biology
• each category is available in 2 versions: line and colored
• the set is available in multiple formats: .AI, .EPS, .PNG, and .SVG

Happy downloading!

What makes this science icon set so usable is the restraint in the color palette. Each icon relies on clean black outlines with a single accent color dropped in as a fill, pink for the flask liquids, mint green for chemical solutions, dusty red for thermometers and vials, and soft blue for molecule diagrams and lab goggles.

That consistency means every icon reads instantly at a glance, even at small sizes, because the eye only has to process one shape and one color cue per symbol.

The subject matter covers a genuine spread of laboratory and scientific imagery: an Erlenmeyer flask, a round-bottom flask, a test tube, a rack of vials, a hexagonal molecule structure drawn as connected nodes, a benzene ring, a thermometer, safety glasses, a Bunsen burner setup, a syringe, a dropper, and a small labeled bottle.

Together they sketch out chemistry and biology in equal measure without leaning too hard on any one discipline, which is exactly why the existing set splits things into chemistry, physics, and biology groupings.

This kind of icon set earns its keep on projects that need to communicate “science” quickly and cleanly rather than photorealistically.

Think educational platforms, school and university websites, chemistry tutoring apps, lab equipment e-commerce listings, pharmaceutical landing pages, science blog headers, or presentation decks for research and academic work.

The line-and-fill style also suits infographics well, since the icons can sit next to data points or process steps without competing with charts or text for attention.

Because the stroke weight and corner rounding are consistent across every icon, they hold together as a set even when you only pull out three or four for a single layout, say a flask, a molecule, and a thermometer to illustrate a lab results page.

Adjusting Colors and Weight to Fit Your Brand

If your brand palette does not run to pink and mint, swapping the fills is straightforward.

Open the icon in a vector editor, select the colored fill shapes directly rather than the outline paths, and recolor them to match your brand accent.

Because the fill is usually a simple shape sitting behind or within the outline, this is typically a one-click swap per icon rather than a full rebuild.

If you need a monochrome version for a favicon, a button, or a dense UI where color would be noisy, you can delete the fill entirely and keep just the outline, which still reads clearly thanks to the bold stroke weight.

For icons that need to sit inside circles or rounded squares as app icons or category badges, group the artwork and center it inside a simple background shape, then export that as one flattened unit so the padding stays even across the whole set.

When pairing these with other design elements, keep the accent colors as your guide.

Buttons, section dividers, or headline underlines in the same pink, mint, red, or blue will tie the icons back into the rest of a page rather than leaving them looking like decoration dropped on top.

Pair them with a simple sans-serif for labels underneath each icon; the geometric, evenly weighted linework matches cleanly with grotesque or humanist typefaces used in most educational and healthcare interfaces.
