Laboratory Equipment Icons - Flask, Petri Dish & Pregnancy Test Diagram #3069134 (License: Personal Use)

This line-art illustration depicts three fundamental laboratory items: a stoppered Erlenmeyer flask containing a dotted liquid (suggesting a solution or culture), a petri dish with three distinct bacterial colony morphologies, and a lateral-flow pregnancy test showing both control and test lines. The clean, schematic style makes it ideal for educational materials where clarity and recognition are prioritized over realism.

Used in educational websites, textbooks, or infographics explaining basic lab procedures, microbiology, or diagnostic testing. Matches user intent for visual aids in STEM learning, especially for middle school to undergraduate levels.
