WHEATON® Premium Rubber Stoppers
Stoppers Rubber Stoppers
Ultra-pure rubber stoppers made from a bromobutyl rubber compound containing the highest level of chemical purity. These stoppers demonstrate very low levels of moisture absorption and extractables.

  • Compatible with Water For Injection (WFI) applications
  • Free from natural rubber or natural rubber latex

They are ideal for use in most lyophilisation applications. Complete coat rubber stoppers are completely coated with a fluorinated polymer that has barrier properties similar to PTFE.

The fluorinated polymer coating is all that comes in contact with the sample. Chemical reactions due to unwanted interference with the rubber itself are virtually eliminated.
