A woman is shown from the chest up in a laboratory setting, wearing a bright green sweater and blue gloves. She is placing small tubes into the holes of a gray plastic rack. The rack has a grid of holes, and she carefully inserts the tubes one by one. She is looking directly at the rack as she works. The lab environment includes bright overhead lighting, white walls, and a visible air conditioning vent on the ceiling. She has a lanyard around her neck with writing on it. Other equipment is partially visible on the lab bench, including a yellow tube cap.
