Daikyo® RUV and RSV Stoppers

Enhanced Pharmaceutical Components

Daikyo Ready-to-Use-Validated (RUV)® and Ready-to-Sterilize-Validated (RSV)® components are manufactured using clean, high-quality elastomer formulations that are washed and sterilized to help reduce the manufacturing footprint, streamline processes, outsource risks around component preparation, and reduce bioburden associated with aging facilities and inflexible plant layouts.

Daikyo RSV components are put through Daikyo’s highly automated wash processes and undergo automated visual inspection to meet a tight particulate specification. Daikyo RSV may help: 

  • Improve regulatory compliance and quality assurance
  • Reduce testing and validation studies
  • Lower levels of particulate
  • Decrease labor, utility and maintenance costs

Daikyo RUV components are steam-sterilized and go one step further than RSV in risk reduction through the provision of line-ready components. Sterilized Daikyo RUV components, available in small quantities and commercial scale, can provide:

  • The security of integrity-tested packaging systems
  • Convenient quantities to enable manufacturing flexibility
  • Reduced equipment and plant footprint
  • Simplified, more efficient processes
