Providing precise, flexible, and secure solutions for your filling process

Our single-use sterile filling bags include high-level buffer bags, filling tubing, and filling needles as components, utilizing a super-clean production process to ensure the cleanliness of the single-use filling bags. As modular components in the formulation filling process, these bags offer advantages such as reduced contamination risk, increased operational flexibility, and shortened changeover times, expediting the drug development and market entry processes.

Compared to traditional stainless steel systems, single-use systems offer the following advantages:

  • More flexible operation
  • Higher safety standards
  • Shorter production cycles
  • Lower initial investment costs

The filling bags produced by LePure Biotech are highly regarded. As modular components in the process of single-use filling systems, they combine flexibility with outstanding safety, meeting regulatory demands for pharmaceutical companies to continually reduce the risk of cross-contamination and decrease the need for cleaning validation.
