Surface Treatment

A protective barrier between the contents and the glass component

Surface treatment refers to a process by which the entire inside surface of a container is deactivated via silanization or siliconization.

The coating provides a protective barrier between the contents and the glass, eliminating active sites on the glass that could potentially react with its contents.

DWK Life Sciences also has the ability to provide ammonium sulfate treated glass which protects against aqueous products that can react with alkali metal ions that are  found in glass.

Convenience & Flexibility

  • Minimize the interactions between the product and container
  • Siliconization ensures higher restitution rate down to the last drop
  • Silanization lubricates the vial and protects against alkalization
