Global Standards in Sizes and Formulations
Our range includes various specifications such as 13mm, 20mm, 28mm, 32mm, and specialized designs like SPC, 12Y, 24mm, 26mm. Available in grey or red, utilizing high-purity Bromobutyl or Polyisoprene formulations for maximum drug stability.
Packaging and Sterilization
In light of ever-evolving requirements for drug packaging, Huaren not only meets the demands of current pharma trends, but goes beyond them by offering ready-to-sterilization (RTS), ready-to-use(RTU).
READY-TO-STERILIZATION (RTS)
Optimizing process efficiency and cost management. All RTS components guarantee a very high standard of particulate and biological cleanliness, giving customers the freedom to focus on their core manufacturing and filling processes.
READY-TO-USE (RTU)
Greater process efficiency and reduced total cost. RTU components not only simplify stock management and operational planning: the increased efficiency, flexibility,and security of supply chain will also result in faster lead times and a reduction of risk and labor costs.
