Biopharma supply, reimagined.

Enter a climate-neutral factory
for best-in-class filters.


Strengthening Biopharmaceutical Supply Chains with Regional Manufacturing

In today’s global landscape, supply chains can be vulnerable to a variety of destabilizing factors. To best service our customers, we are regionalizing our production network to ensure access to high-quality products when they are needed, where they are needed—regardless of global events.

Our new 12,500 m² regional manufacturing facility in Blarney, Ireland, will serve the filtration needs of our EMEA customers manufacturing monoclonal antibodies and recombinant proteins, cell and gene therapies, vaccines, and other therapeutics.

This new facility will manufacture our best-in-class filters, including virus filters (Viresolve® Pro Devices), tangential flow filtration filters (Pellicon® 3 Cassettes), and sterilizing filters (Opticap® XL and XLT Filters with Durapore® or Millipore Express® Membranes) - opening Q3 2025.

Supporting Supply Chain Security, Consistency, and Reliability

This new facility is part of our growing global-local hybrid manufacturing infrastructure combining global oversight with regional production. With manufacturing capabilities that are redundant to those in our Jaffrey, New Hampshire (USA) site, the Blarney facility will provide EMEA customers with equivalent, locally manufactured filtration products. The local supply chain support provided by the Blarney facility will enable:

  • Increased production capacity for filters
  • Dedicated regionalized capabilities
  • Minimized disruptions with redundant manufacturing
  • Streamlined logistics and shorter transportation distances

The facility, located within the 70-acre Blarney Business Park, encompasses 3,100 m² of clean room space (ISO 8), 1,048 m² of analytical lab space, and automated warehousing capabilities in buildings designed to meet EU nearly-zero energy building standards.
