Green Liquid in Laboratory Flask - Scientific Experiment Visualization #3069291 (License: Personal Use)

This vector illustration depicts a classic Erlenmeyer flask filled with a dark olive-green lower layer and a lighter lime-green upper layer, indicating possible density-based stratification or phase separation. The transparent glass highlights refraction and depth, commonly used to represent lab-based biological or chemical processes such as algal biofuel research or pH indicator experiments.

Used on educational websites, science blogs, or biotech product pages to visualize laboratory procedures, sustainability initiatives, or classroom demonstrations; matches user intent for visual aids in STEM content.
