Sani-Tech ® ultra-pure, platinum-cured silicone stoppers outperform standard neoprene
and rubber stoppers in critical process and laboratory applications in terms of lifeexpectancy,
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.
