Safe Snap Amp Snapper.

A simple and effective device for safely opening glass ampoules.

The plastic case completely encloses the glass ampoule, holding the neck in place so that it can be broken with a simple snap.

The snapper can then be easily opened so that the ampoule can be removed, or the amp snapper can be locked in the open position (by means of a clip on the back) and contents of the ampoule can be drawn up in situ.
Always have the dot on the amp facing out.
