Septa for Serum Vials (Stoppers)

The septa (or "stoppers") on this page are meant for closing serum vials. A septum is placed on the neck of the vial, a seal is placed on top, and the seal is fastened with a crimping tool.

Septa come in a variety of styles and colors. What we currently carry have long plugs with notches (or legs) which help with the freeze drying process. They work fine for general use.
