Ampoule Opener

An ampoule opener is a small cap that snaps a glass ampoule open cleanly and keeps the broken neck contained, so no fingertip goes near the break. Openers come in neck sizes, not one size.

What it’s for

If anything you use comes in snap-top glass ampoules, this saves fingertips.

What to check in the listing

Only worth it if something you use actually comes in snap-top glass. If it does, check the opener covers your neck size — they aren't one-size.

If you're not sure which water a vial needs, or how long an opened bottle lasts, read Bac water vs sterile water vs saline (and which to buy) first.
