Amber Glass Prescored Ampules-WTN 176799

A WHEATON ampule is an all-glass container that can be hermetically sealed to preserve sample purity and extend sample shelf life. WHEATON ampules are ideal for standards packaging, environmental standards, diagnostic standards and cryogenic storage. These amber ampules protect light sensitive samples and help reduce sample contamination due to their ultimate tamper-evident seal. WHEATON ampules are offered in sizes ranging from 1 to 50 mL capacity. Two sealing methods can be used on these amber standard ampules. Tip Sealing Method: Holding the ampule body, insert the ampule stem into the sealing flame. Heat the stem 3-4 mm from the top of the ampule, until the melted glass fuses into a smooth dome. The Pull Seal method: Hold top in the fingers of one hand. The flame should be approximately one-third of the way from the Gold Band and your fingers. As the glass softens, continue to rotate the ampule while pulling the top off the ampule. This will require very little force, allowing the glass to seal itself. As the top separates from the ampule, sealing occurs. This method can be used for all Ampule configurations.
