Ultraviolet Lamp Tube

Physics This is a narrow tube of glass with black rubber or plastic caps on either end; these are lined with what appears to be cork. At one end of the glass there is a small manufacturer’s label affixed to the exterior of the glass. This rod possibly contains mercury gas. This is a small yellow tag with a cotton string attachment, and likely is the tube’s original tag.
