Silicone Stopper Assemblies


Sani-Tech ultra-pure, platinum-cured silicone stoppers outperform standard neopreneand rubber stoppers in critical process and laboratory applications in terms of life expectancy, consistency, and purity. Sani-Tech silicone stoppers are fully autoclavable and sterilizable and will not crack, cause spallation, or release particulates that could cause process contamination or lost product.

Sani-Tech silicone stoppers can be supplied with cored holes for use with specially designed dip tubes or vent configurations. Custom identification markings can also be utilized to help differentiate supply lines.

Sani-Tech Silicone Stoppers Characteristics
The manufacturing process of the silicone stoppers is carefully controlled from receiving through production and inspection and lot traceability is readily accessible in all stages through batch number assignments.

Saint-Gobain Performance Plastics ISO 9001 manufacturing facilities have the ability tocreate a wide variety of customized silicone stoppers including color coding and coring options to fit the demanding applications of the pharmaceutical, biotechnology, and laboratory environments.

Biocompatability
Sani-Tech® ultra-pure silicone stoppers are manufactured from a biopharmaceutical gradeof silicone materials and are fully characterized from a biological, chemical, and physical standpoint. Sani-Tech® stoppers are tested to specifications including USP Class VI and FDA 177.2600 criteria. Sani-Tech® ultra-pure silicone stoppers have a masterfile with the U.S Food and Drug Administration.
