Wheaton ampules are all glass containers that can be hermetically sealed to preserve sample purity and extend sample shelf life. Wheaton ampules are ideal for standards packaging, environmental and diagnostic standards, lyophilization and cryogenic storage. These ampules protect against sample contamination due to their tamper-evident seal. A gold band on the stem of the ampule indicates that the ampule is pre-scored to facilitate snapping off the top of the ampule eliminating the need to file the ampule.
Tip Sealing Method for Standard Ampules: While holding the ampule body, insert the tip of the ampule stem into the sealing flame. Heat the tip approximately 3-4mm from the top. Gently rotate the ampule while heating the tip until the melted glass fuses into a smooth dome.
Pull Seal Method for Funnel-Top Ampules: In addition to easier filling, the funnel-top ampule is easier to seal using the Pull Seal method. Hold the funnel top with one hand and the body of the ampule with the other hand. Insert the center of the ampule stem into the sealing flame. As the glass softens, rotate the ampule while pulling the funnel top off. This will require very little force and will allow the glass to seal itself. This method can be used for all ampule configurations.
