Test Tube with Red Liquid - Scientific Lab Illustration #244824 (License: Personal Use)

This minimalist vector graphic depicts a conical-bottom test tube partially filled with two-toned red liquid-suggesting layered or gradient content-and a pipette positioned above, releasing a single droplet. The clean black outlines and flat color scheme emphasize clarity and scientific communication, making it suitable for educational or diagnostic contexts. The design avoids realism in favor of symbolic representation.
