About the Sample black outline icon
A rounded test tube lies at a diagonal with a looped stopper at its top, a banded label ring below the neck, and liquid filling the lower half with a wavy surface line. A single teardrop with a small highlight sits alongside it. Use it for laboratory dashboards, blood donation pages, diagnostic and screening apps, medical checkup forms and research reports.
The tube runs corner to corner across the frame while the drop occupies the lower right, giving the icon a balanced two-object layout with clear negative space. It matches syringe, microscope and lab report icons in the library. Keep it above 24 px so the stopper loop does not fill in.
This is the black outline version of the sample icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
