Now made of PE-HD instead of stainless steel, so no corrosion by acids or lyes. Hinged lid allows for a clean closure. Freely rotatable cap comes in different thread sizes for a wide variety of containers. Safety lance ensures clean outflow without contaminating the container opening. With electrically conductive funnels (black), the lance facilitates a safe additional grounding of the contents. Models in black are made of electrically conductive PE-HD and have a ground connection to prevent sparking hazards.
