Wheaton glass serum vials, amber

These are the preferred containers for lyophilization. There are three essential variables to good Lyophilization: Heat Transfer, Sealability, and Water Vapour Transmission Barrier.

Manufactured from Wheaton borosilicate moulded glass (meets USP Type I standards).

• Heat Transfer - a Wheaton Glass serum vial, as opposed to glass serum bottles, plastic serum bottles, and other containers has a very consistent thin wall and bottom. This attribute of a Wheaton glass serum vials allow the heating phase of the lyophilization process to take place rapidly and effectively.
• Sealability  - Wheaton glass serum vials feature a "blowback" feature in neck and bottom. This allows for a 2 or 3 legged lyophilization stopper to be securely and evenly seated in the mouth of the vial during the lyophilization process. An uneven stopper may results in water vapour entering back into the vial once stored. Additionally, these serum vials come in standard crimp finish sizes, for compatibility with various standard aluminium seals and crimping tools.
• Water vapour Transmission Barrier - Wheaton glass serum vials are made from premium, low extractable, borosilicate glass, which offers a superior barrier to water vapours. The vials are available in either clear and amber for UV light transmission applications.
• Autoclavable - These vials can be autoclaved, by dry heat, by chemical, by gas, or by radiation.
