About the Chemical Tube black outline icon
A narrow test tube with a rounded bottom and a flared rim is filled to just above the middle with liquid drawn as a wavy line, scattered bubbles float inside the glass and three more rise above the opening. It reads as chemistry, reactions, experiments and lab testing. Use it in science education apps, laboratory and pharma sites, research report slides, medical testing dashboards, and product ingredient pages.
The wavy fill line separates liquid from empty glass without any color, and the bubble dots vary in size so the reaction feels active. It pairs with flask, microscope, molecule and dropper icons from the same lab set. Keep the escaping bubbles inside the canvas padding when you resize.
This is the black outline version of the chemical tube icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
