ABSTRACT:
A laboratory workbench includes a housing bounding a working space. The working space communicates with the exterior through a window bordering the working space on one of its sides thereof. A fan produces a flow of air in the working space and out the window. A protective screen is arranged on the housing in such a way that it can be moved. Specifically, the protective screen is mounted on the housing in the top area of the working space window in such a way that the protective screen can be moved between a hanging position at least partially covering the window, and a folded-up position. In the folded-up position, the protective screen projects into the housing in a substantially horizontal position plane. In one embodiment, an expansion screen is movable attached to the protective screen and has reach through openings formed therethrough.
