Silicone Stoppers

 
 

Ultra-pure platinum-cured silicone stoppers outperform standard neoprene and rubber stoppers in critical laboratory applications. These silicone stoppers are autoclavable and will not crack, spallate or release particulates that can cause process contamination.

Manufactured from our own brand of silicone resin, Sani-Tech ® platinum-cured silicone stoppers comply with USP Class VI, USDA, FDA, European Pharmacopoeia 3.1.9 and ISO 10993 standards.

All stoppers can be supplied with cored holes for use with platinum-cured silicone tubing, dip tubes or vents.

  • Platinum-cured silicone stoppers resist cracking and spallation and reduce the possibility of particulate contamination
