Is my ampule intact? How can I tell?
If the meniscus "bubble" is not broken, then the ampule is intact and usable. To test the meniscus, use a glass Pasteur pipet and gently touch the bubble. If the glass pops and breaks, then the ampule was sealed. If it goes straight through to the bottom of the ampule with no resistance, then the seal was broken during transit.
