Lab Sample Preparation: Pipetting Liquid into Microcentrifuge Tube #239360 (License: Personal Use)

This illustration depicts a common laboratory procedure where a pipette transfers a pink-colored aqueous solution into a sterile microcentrifuge tube. The tube shows distinct liquid layers, suggesting phase separation or gradient preparation, often used in DNA extraction, protein purification, or cell lysis protocols. The clean, schematic style emphasizes clarity for educational or protocol documentation purposes.

Used on science education websites, lab protocol pages, or biotech product documentation to demonstrate proper pipetting and sample handling. Matches user intent for learning basic lab techniques or visualizing steps in molecular workflows.
