Seen in numerous episodes of the Original Star Trek Series

I purchased this online.

This is a really fantastic kit that I am really happy with. All of the pieces are made out of machined aluminim. The Hypo spray even makes a hiss noise when you push down the plunger. I have not yet finished working on the ampules. I still need to fill them with liquid and paint the caps. From what I can tell, the ampules are inaccurate. Maybe they appear as they do in this kit in later episodes, but from the early episodes, the ampules appear to be sealed acrylic tubes. Either way, that's a small distraction from the overall kit.
