Scientist Working with Test Tubes in Laboratory Setting

Close up photo of a gloved hand in a laboratory setting, holding a test tube and a pipette. There is a microscope, a test tube rack containing test tubes filled with liquids of various colors, and several small glass vials. This image is well-suited for projects about science, medicine, research, laboratory work, and health and wellness topics. The scene is lit in blue and the composition conveys a sense of controlled experimentation and sophisticated technology.
