Perspectives In Aseptic Manufacturing: Establishing A Container Closure System — Engineering For Integrity

By Eric Kurtz, Manager Technical Product Development

Container closure system design in aseptic manufacturing is rarely straightforward. Selecting a vial and stopper is the starting point, not the solution. As Eric Kurtz, Manager of Technical Product Development, outlines in this article, integrity depends on how elastomeric closures interact with feeding systems and plunger insertion mechanisms, how barrier configuration (RABS or isolator) shapes contamination control requirements, and how component format choices ripple through line design and operational flexibility.

The industry's continued migration toward ready-to-use formats reflects growing recognition that washing and sterilization requirements introduce risk, not just cost. Meanwhile, plunger placement variables including vacuum-assisted insertion, vent tube selection, and headspace modeling carry direct implications for residual bubble size and pressure equilibrium, factors that are easy to underestimate until integrity is compromised.

For teams navigating CCS decisions across the development and commercial production continuum, Kurtz's perspective offers a structured view of where the real engineering complexity resides. Explore the full article to examine these considerations in detail.
