MK METALFREE
Progress through high-tech and precision
MK METALFREE originated in Germany in 1988, founded by Michael Keil as “MK Versuchsanlagen und Laborbedarf,” focusing on biotechnological systems and later on metal-free workspaces and pharmaceutical testing technologies. By 2006, the company had grown significantly, gaining international recognition and ISO certification by 2014.
In 2019, it expanded to the U.S., establishing MK METALFREE Corp. in Phoenix, Arizona, becoming a global leader in glove testing systems.
In 2025 we opened our new location in Dublin with the foundation of MK METALFREE IRELAND Ltd. This strategic move strengthens our presence in Ireland and the UK – key markets in the pharmaceutical industry – and brings us closer to our customers.
