The laboratory taps of the Labtap Control series consist of four components: the cylindrical base, the actual fitting, the operating handles attached to it, and the curved spout. The brass bodies are coated with a pearlescent nickel-chrome finish. The position of the handle indicates whether the valve is open or closed at any given time. The spout and the operating handle have the same colour coding, so that they may be clearly assigned to a liquid or gaseous medium.
