SKS Science Products Vacules Clear Glass Pre-Scored Lyophilization Ampules 651502

Ampules are all-glass containers that can be hermetically sealed to preserve sample purity and extend sample shelf life. These clear glass pre-scored lyophilization 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. The clear glass pre-scored ampules are offered in sizes ranging from 1 to 50 ml capacity. These ampules have stems that can be pull-sealed or tip-sealed to close the container. The Gold Band pre-scored feature eliminates filing. These Vacules are designed for freeze-drying, protein hydrolysis, and micro-determination of ketones and amino acids. The long stems provide a convenient means for heat sealing under vacuum. A Gold Band identifies the pre-scored feature, which allows easy opening. This small-volume lyophilization ampule can be flame-sealed or stored with a stopper in place. It is made of low extractable clear borosilicate glass, (meets ASTM Type I Class A and USP Type I standards)
