Injection Molded Silicone Stoppers

Manufactured in a clean room environment, these stoppers are biologically safe and are designed for containers such as carboys, flexible storage systems, laboratory apparatus and bottles, and sampling and storage vessels. Produced using a silicone elastomer that meets Class VI and FDA standards and does not contain any animal ingredients, the stoppers provide long life expectancy and consistent performance. A smooth finish and gap-free surfaces ensure a true seal and a secured environment. The stoppers resist cracking, particle migration, chemical attack, and a wide range of temperatures — from 㫡.3 to 204.4 degrees C. They work well with containers of glass, metal, or plastic and can be sterilized by autoclave or gamma radiation.
