Measuring Liquid Volume in a Graduated Beaker - Science Lab Illustration #1698448 (License: Personal Use)

This illustration depicts a transparent glass beaker filled with light blue liquid, calibrated with evenly spaced horizontal lines and numerical labels (20, 40, 60, 80, 100) indicating milliliter volumes. The meniscus of the liquid aligns precisely with the 50 mL mark, demonstrating accurate volume measurement technique used in scientific experiments.

Commonly used in educational websites, K-12 or college science textbooks, lab procedure guides, and STEM outreach materials to teach measurement fundamentals, unit conversion, and proper use of lab equipment.
