An ampoule is a small glass vial commonly used to hold liquids or solids in a laboratory setting and typically is sealed shut. Ampoules also are used to hold beauty products, medicine or other delicate liquids. They are sealed shut to protect the contents from exposure to air, bacteria and debris or dirt that could contaminate the contents. Opening an ampoule should be done with caution to prevent breaking the glass and spilling the contents.

    Use even and firm pressure to bend and break open the ampoule at the neck.
