Encapsulation

A specialty of Fredericks is the glass encapsulation of hard-to-handle substances. Whether a liquid, solid or gas, Fredericks has the capability of encapsulating extremely small volumes and weights, such as a glass ampule that holds only 4.5 mg of mercury. Additionally, Fredericks has encapsulated ammonia and other challenging materials. Coupled with Fredericks custom ampule forming capability, we can meet your unique encapsulation needs for prototype or higher volume production.

Fredericks also offers complete product packaging, combining custom-filled ampules with your product labeling for market distribution. Fredericks is your best source for advanced glass encapsulation.
