LS Instruments joins Postnova Analytics
20.08.2026German Postnova Analytics GmbH has successfully completed the acquisition of LS Instruments AG. The milestone opens new opportunities for innovation, international growth and product development. Operations will continue unchanged from the company's headquarters in Fribourg, Switzerland, where the existing team will remain focused on developing, manufacturing and supporting LS Instruments' innovative light scattering and microrheology technologies.

LS Instruments has built a strong reputation for providing advanced analytical instruments leveraging light scattering for particle characterization and microrheology applications serving customers in academia, pharmaceuticals, biotechnology, food, cosmetics and advanced materials.
The acquisition combines the scientific expertise, innovative technologies and dedicated teams of both organizations, creating new opportunities for product development, customer support and international growth, creating the leading light scattering portfolio in the industry.
Gabriel Haering, Chairman of the Board of LS Instruments, commented: "I am delighted to communicate the successful completion of this transaction. The acquisition represents an important milestone in the history of LS Instruments and provides a strong foundation for future growth. I am particularly pleased that the company will remain in Fribourg and that our highly educated and experienced employees will continue to develop and enhance the innovative products that have established LS Instruments as a recognized leader in light scattering and microrheology technologies."
Gaurasundar Marc Conley, CEO of LS Instruments, added: "For LS Instruments this is a natural fit. Together, the two portfolios cover the path from fractionated, component-resolved analysis to intact, native sample characterization, with little overlap and significant common ground in light scattering expertise and customer needs. This creates concrete potential for synergies to advance the growth of both organizations. I very much look forward to working closely with the Postnova team to translate this into faster development, broader applications and stronger support for our current and future customers worldwide."
Thorsten Klein, CEO of Postnova Analytics added: "The unique, high-value technologies of LS Instruments — the LS Spectrometer II, DWS RheoLab and NanoLab 3D — are a perfect extension of our existing product portfolio and will be fully integrated into our global commercial, technical support and application-development capabilities. They provide research laboratories worldwide with advanced analytical solutions to address complex measurement challenges, generate deeper insights into materials and formulations, and accelerate the development of better-performing products. We see significant opportunities to further advance these technologies, broaden their applications and make them accessible to an even wider global research community.”
Founded by distinguished physicists Professors Peter Schurtenberger and Frank Scheffold, LS Instruments emerged from extensive research into soft materials. Recognizing the limitations of existing light scattering methodologies in studying concentrated samples, the founders embarked on a mission to enhance the technology's capabilities, ensuring robust characterization of turbid and highly concentrated samples.
The genesis of LS Instruments' technology and product portfolio traces back to pioneering research projects at ETH Zurich and the University of Fribourg. Groundbreaking innovations such as Echo DWS in the DWS RheoLab and modulated 3D cross-correlation in the LS Spectrometer and NanoLab 3D have since been patented, underscoring our commitment to technological advancement.
Established as a Swiss public limited company in 2010, LS Instruments has fostered a global clientele across 34 countries.
