Available in three sizes, SnapIT has been developed to offer healthcare professionals a safer way to open ampoules. Each version features a convenient key-ring for attachment to lanyards or chains. SnapIT is easy-to-use and can help reduce the rate of injuries encountered when ampules are opened by hand by keeping both hands away from an ampoule's sharp edges. One hand holds the base of the ampoule while the other uses SnapIT to remove the lid: 1.Insert 2.Snap 3.Eject SnapIT Ampule Openers feature a replaceable multi-use O-Ring which can be damaged by shards of glass from opened ampoules.
