Laboratory test icon: two graduated test tubes and a sample drop inside a circle
About the Laboratory Test black filled icon
Two capped test tubes stand side by side inside a thin circle, one tilted and one upright, each marked with a column of dashes that read as volume graduations, with a single teardrop of sample floating to the left. Together they communicate analysis, screening and measured results. Suited to lab report pages, blood test booking flows, diagnostics dashboards, pharma product sheets and science lesson decks.
The badge framing and the repeated dash scale give the mark rhythm, while the tilted tube breaks the symmetry so the pair does not look like a plain bar chart. Combine it with microscope, flask and DNA icons across a research set, and drop the graduation dashes if you need it below 24 px.
This is the solid black filled version of the laboratory test icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
