About Us

Applied Microspheres Building

The foundation for Applied Microspheres GmbH was laid in 2001 with the establishment of BS-Partikel GmbH in Wiesbaden, Germany. Renowned for its exceptional production of particle standards, BS-Partikel entered into a strategic partnership with Applied Microspheres BV to become a leading supplier of custom-made particle technology products. In 2023, BS-Partikel acquired Applied Microspheres and Distrilab Particle Technology BV, a recognised supplier of particle-based products across Europe. These parties have since formed a unified entity, Applied Microspheres GmbH, based in Mainz, Germany.

Our meticulously designed portfolio caters to the diverse needs of our valued clients. This range covers various sectors and industries including pharmaceutical, biotechnology, diagnostics, semiconductor, pulp and paper, food, and shipping, as well as the broader field of particle technology research. At Applied Microspheres, we pride ourselves on being the ideal partner to develop bespoke solutions, tailored to the specific requirements of any particle-related challenge.
