Item Number: A1104-1




This 1mL ampule is made of clear Wheaton 33® expansion low extractable borosilicate glass that can be hermetically sealed to preserve sample purity and extend sample shelf life. It is ideal for standards packaging, environmental standards, diagnostic standards, and cryogenic storage. The ampule helps reduce sample contamination due to the ultimate tamper-evident seal. The Gold Band® pre-scored feature eliminates filing. Either of two sealing methods can be used on this ampule. The tip sealing method involves holding the ampule body and inserting the ampule stem into a sealing flame, heating the stem 3-4mm from the top of the ampule until the melted glass fuses into a smooth dome. The pull seal method involves holding the top of the ampule in the fingers of one hand with the sealing flame approximately one-third of the way from the Gold Band® and your fingers. As the glass softens in the flame, rotate the ampule while pulling the top off the ampule, allowing the glass to seal itself. Meets USP Type 1 and ASTM Type 1, Class A standards. Autoclavable. Material: Wheaton 33® Low Extractable Borosilicate Glass. Color: Clear. Glass Type: Type 1. Diameter x Height: 10.5 x 67mm. Capacity: 1mL. Wheaton® #: 176772.
