¡á Á¦Ç°Æ¯Â¡(Features) * 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 ampules help reduce sample contamination due to their ultimate tamper-evident seal. * Wheaton ampules are offered in sizes ranging from 1 to 50 mL capacity. * Our line includes pre-scored Gold Band¢ç, Funnel-Top, Standards and glass Cryules¢ç and Vacule¢ç cryogenic ampules. Sealing 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. Sealing Funnel-Top Ampules * The funnel-top ampule allows not only easier filling but also easier sealing. * To seal, use the Pull Seal method. Hold the funnel op 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 funnel top off the ampule. * This will require very little force, allowing the glass to seal itself. * As the funnel top separates from the ampule, sealing occurs. * This method can be used for all Ampule configurations. Design Features * Wheaton ampules are designed for a wide variety of applications; additionally, we can develop ampules to fit your special requirements. * Contact Wheaton for more information. * These ampules have stems that can be pull-sealed or tip-sealed to close the container. * The Gold Band¢ç pre-scored feature eliminates filing. * Wheaton "320" amber borosilicate glass (meets USP Type 1, Class B standards) for protecting light-sensitive samples.
