Borosilicate5.0 GlassAmber Clear Glass Ampoules Cosmetic Ampoules

Ampoules are glass laboratory vials composed of low extractable clear borosilicate glass that can be sealed to maintain sample purity and extend sample shelf life. These clear glass laboratory vials are ideal for standard packaging, environmental standards, diagnostic standards and cryogenic storage. These glass lab vials feature a pull-seal or tip-seal stem to close the container and help reduce sample contamination thanks to their final tamper-proof seal. The gold band on the 1ml and 2ml ampoules identifies the pre-scoring function for easy opening. Clear glass ampoules designed for freeze-drying, proteolysis, and micro-measurement of ketones and amino acids. This small volume freeze-dried glass laboratory vial can be flame sealed or stored with a stopper

The development of ampoules is based on the concept of the Teflon jug for holding high molar concentrations of hydrofluoric acid [3], for holding metal containers that corrode and/or ignite glass and/or contaminate themselves, corrode or decompose metal containers containing reagents Chemicals do not passivate metals reliably and predictably or not at all by rapidly forming a new layer of inert compounds on the metal surface.

Many 14-dihydromorphone opioids (such as hydromorphone and oxymorphone), light-sensitive chemicals such as various silver salts, can be packaged in ampoules of smoked glass, which is manufactured with added UV filters and Other types of light chemicals, or the top and bottom made of opaque glass (usually painted with opaque paint) and the rest of the ampoule wrapped in thick paper.
