A woman in a white lab coat demonstrates the use of a micropipette in a laboratory setting. She is standing at a white counter. On the counter in front of her are a clear glass bottle, three small amber bottles labeled "2," "1," and "B19," and an identification badge on a green lanyard that hangs around her neck. The woman picks up the micropipette, adjusts the volume setting, and points to the pipette tip. The lab has white walls and a suspended ceiling with a vent. There are shelves and cabinets behind the woman.
