A person in a white lab coat and blue gloves is seen pressing a test tube on a blue vortex mixer in a laboratory. The mixer is on a white counter next to a computer keyboard and a computer monitor mounted on the wall. A container labeled "Вазочки для контроля 0.5 мл" is also visible on the counter. Behind the counter, there is a window with closed blinds. A security camera is mounted on the ceiling.
