Sterile Filtration / PUPSIT


Reasons to attend this conference:

  • You learn why PUPSIT found its way into the revised EU GMP Annex 1
  • Inspectors discuss what they expect from the implementation of PUPSIT in pharmaceutical companies
  • Pharmaceutical companies present their strategy for PUPSIT implementation in case studies


PUPSIT is one of the most intensely and controversially discussed topics in the revised EU GMP Annex 1. But why do we have this intense discussion. Do the expectations of the regulatory authorities regarding the safety of sterile filtration differ from the practice in pharmaceutical companies? If so, why? Does PUPSIT now have to be implemented 100% in every case or where are there exceptions? If so, how must these be justified? Several case studies from pharmaceutical companies focus on the companies' specific strategies for implementing the current PUPSIT requirements.

Target Audience

The event is directed at specialists from the pharmaceutical industry as well as at engineers and planners who have to deal with sterile filtration and especially PUPSIT in their daily practice.
It particularly addresses the departments:

  • Production
  • Quality assurance
  • Engineering / Technology

Detailed Programme

Presentations - 28 March 2023

PUPSIT, or Not to PUPSIT….?
Dr Simone Biel, Merck
Since the first draft of the new Annex 1 was published, the pre-use post-sterilization integrity test (PUPSIT) of a sterile filter was one of the most discussed topics related to the Annex 1 revision.

  • How to interpret the Annex 1 PUPSIT clause?
  • Why is it a debate?
  • And what is the industry’s answer on PUPSIT?

Practical Aspects of Pupsit Implementation
Guillaume Lesage, Merck
Intricated with PUPSIT are several technical challenges related to the preparation of filtration systems:

  • Dry leak testing, flushing dynamics, Integrity test selection and dilution/drying challenges.
  • Filtration assembly characterization insights
  • Filter integrity test limits specific to single-use assembly.
