Sani-Tech® ultra-pure platinum-cured silicone stoppers outperform standard neoprene and rubber stoppers in critical laboratory and process applications. These long-life silicone stoppers are fully autoclavable and sterilizable and will not crack, spallate or invoke particle migrations that can cause process or product contamination. All Sani-Tech silicone stoppers can be supplied in a solid configuration or with cored holes for use with dip tubes or vents. Custom identification markings can also be supplied to help differentiate supply lines.
