Thí nghiệm

A focused Vietnamese female organic chemistry student, in her early 20s, wearing a clean, modest white lab coat, professional safety glasses, and blue nitrile gloves. She is carefully pipetting a transparent liquid from a small vial into a glass beaker on a lab bench. The beaker contains another clear liquid, and a subtle color change (e.g., pale yellow to light green) is beginning to appear. In the background, a modern, well-organized organic chemistry laboratory is visible, with neatly arranged glassware, a functioning fume hood, and various chemical reagents stored safely. The lighting is bright and clean. The student maintains a natural, professional pose, her well-formed hands holding the pipette with precision, demonstrating perfect anatomy, correct proportions, and a natural body posture. This image is fully clothed, appropriate attire, safe for work, professional, modest, and family-friendly, captured with high-quality, professional photography and sharp focus.
