I use an ampule opener, but it seems like I break about two or three during a cycle. When it works the top snaps off and i draw from the vile below. When something goes wrong the entire ampule breaks into a million pieces and the sust gets all over my fingersand hands and I can't draw anything- total loss. Just wondering if there is a better method. For me, its so tough getting gear at all, it seems like a crime to lose it this way.
