Northstar Luna Tubing.

NS-145 Luna is a clear glass that fluoresces blue under a U.V. light source. This glass does contain some air content, although stable and can be used in any type of flame. We recommend using an ultraviolet L.E.D. flashlight with a 365Nm-395Nm range for the brightest blue glow. No uranium is used in this glass.
