In this session, Protak Scientific and SKAN brought together two complementary areas of expertise to explore H₂O₂ isolator cycle development.

The session focused on real-world approaches to cycle development, requalification, and building more defensible validation strategies. It highlighted how combining quantitative tools such as Enzyme Indicators (EIs) and CFD modelling alongside traditional Biological Indicators (BIs) can provide a clearer understanding of what’s happening inside an isolator, helping to reduce uncertainty and strengthen validation evidence.

Presented by specialists from both organisations, the discussion was grounded in practical application rather than theory.

This Session Covered:

  • Practical validation challenges in isolator and barrier systems.
  • Lessons from real-world applications.
  • A case study on bio-decontamination homogeneity assessment using EIs and CFD simulations.
  • How quantitative EI data can strengthen qualification and requalification strategies alongside BI data.
