Methods of Sealing
For the Tip-sealing method- while holding the ampule body, heat the tip in the flame approximately 3-4mm from the top. Gently rotate the ampule while heating until the melted glass fuses into a smooth dome. The tip-sealing method is better suited for short stem ampules.
For the Pull-sealing method- heat the center of the ampule stem in the flame. As the glass softens, rotate the ampule while pulling the top off. This method may be used to seal all ampule configurations.
Instructions for opening ampules
To open an ampule, grasp the stem in one hand and the body in the other, placing thumbs tip-to-tip near the constriction. Using thumb tips as a hinge, bend the stem and the body to break the ampule open. A special ampule file is not required.
