Disposable single-use components are essential for biopharmaceutical manufacturing, unfortunately are commonly affected by contamination from extractables and leachables that adversely affect efficacy and quality.
The implementation of a diamond-like carbon coating could minimizes or eliminates the formation of leachables in single-use components.
Understand the adhesive and mechanical properties of the DLC coating on ILC Dover 5L vessels as well as demonstrate that the 5L vessels are more biocompatible for cell growth vs uncoated vessels
Understand the complete set of physicochemical properties of DLC coated ILC Dover materials as well as obtain processing parameters that optimize the DLC coated materials in terms of biocompatibility and mechanical performance under worst‐case scenarios
Develop a standardized approach for depositing diamond like carbon coating on single use vessels to minimize the release of leachables
Minimize the need for extensive functional tests typically required for disposable vessels
