In this shared workspace, various professors and students work in a sterile environment. Everything under the hood has been sterilized using an ethanol solution. The ultraviolet (UV) light kills any remaining bacteria once the hood is turned off, keeping the workspace clean when not in use. This type of sterile workspace is important when data for an experiment relies on the substances in question being uncontaminated.
