Changes to Merck Life Science, Millipore and Sigma-Aldrich Legal Entities: Impacts on Web Shop and Ordering

On July 1, 2020, the commercial business of Merck Life Science in the UK is being restructured. This business is currently operated by three legal entities, Merck Chemicals Limited, Millipore (UK) Limited, and Sigma-Aldrich Company Limited.

The commercial business will be consolidated into Merck Chemicals Limited, which will at the same time be renamed to Merck Life Science UK Limited.

You will benefit from this development since Merck will serve the customers of its Life Science business in the UK (and Ireland, to the extent Merck currently serves Irish customers from UK legal entities) via one legal entity, as opposed to three entities, none of which could provide customers with access to the entire Merck Life Science portfolio.
