Pharmaceutical Butyl Stopper

We are offering here the Pharmaceutical Butyl Stopper is commonly used for manufacturing rubber stoppers used for sealing medicine vials and bottles. It is chemically inert and non polar, absorption of drugs or water is low. Studies indicate that bromobutyl rubber-based stoppers have much lower drug turbidity than regular butyl stoppers. Choosing a suitable stopper material is very essential for studies related to denitrification coupled to methane oxidation. In some cases stoppers are replaced with sterile PTFE mininertvalves or PTFE-faced grey butyl rubber stoppers, for containment of voltiles. The offered Pharmaceutical Butyl Stopper is very efficient and easy to use.
