We’re excited to announce that Nelson Labs will be exhibiting together with our sister company Sterigenics at Pharmapack – booth D17 – Hall 4, at Paris Expo, Porte de Versailles in Paris, France 21 – 22 January 2026.
Join our presentations!
Presentation #1 |Nelson Labs
Title: Extractables and Leachables for Combination Products
Date/Time: Thursday, 22 January 11:30 AM – 12:00 PM
Location: Learning Lab 4A89
Abstract:
A significant part of recent pharmaceutical products are combination devices, for which the packaging also serves as delivery system for the drug product to the patient. Impurities may be released from these polymeric systems (extractables) and may end up in the drug product (leachables) and as such pose a safety risk to the patient. In this presentation, an overview of different types of combination devices will be given, followed by a discussion on the importance of extractables and leachables testing. The regulatory landscape (and relevant guidelines) will be reviewed for both EU and US markets. Lastly, relevant parameters for these studies such as extraction time, temperature and extraction solvents will be discussed, while these will be demonstrated in a practical case study.
Presenter: Pieter Van Wouwe, Scientific Expert, Nelson Labs

Pieter Van Wouwe received his Master’s degree and PhD in Bioscience Engineering at the University of Leuven in 2016. Afterwards, he started working at Nelson Labs as a project manager, initially mainly involved in scientific interpretations and the reporting of analytical results. Over the years, he has expanded his role and became responsible for designing pharma-related extractable and leachable studies for both packaging materials and process materials, as well as for medical devices and combination devices. Providing support for extractables and leachables studies to both biopharmaceutical and medical device companies is currently one of his main day-to-day activities
Presentation #2 | Sterigenics
Title: Optimizing Ethylene Oxide Sterilization: Sustainable Solutions for Pharmaceutical Packaging and Drug Delivery Devices
Date/Time: Thursday, 22 January 1:50 PM to 2:20 PM
Location: Learning Lab 4A89
Abstract:
Ethylene oxide (EO) remains the sterilization method of choice for approximately 50% of all single-use medical devices worldwide, thanks to its excellent material compatibility and scalability. As the industry advances toward more sustainable practices, innovative optimization strategies are helping reduce EO use while maintaining required sterility assurance levels (SAL) to help ensure patient safety.
