About TESTA Analytical Solutions
TESTA Analytical Solutions is a technology provider and specialist in high-performance liquid chromatography (HPLC, uHPLC, LC/MS), GPC/SEC detectors, and non-invasive real-time flow meters for applications such as ion chromatography and flow chemistry. The portfolio also includes Brookhaven brand instrument systems for particle size analysis, light scattering (DLS/SLS/MALS), and zeta potential measurement. With over 30 years of experience in separation science and particle size analysis, in addition to standard products, the company develops custom systems and OEM instrument kit components that are installed in devices from well-known analytical and process instrument manufacturers worldwide. In addition to sales, TESTA offers on-site installation, training, system validation, preventive maintenance, application support, as well as calibration and performance validation services (3-point and 10-point calibration). The headquarters is located in Berlin, while the main site for calibration and validation services is in Teltow near Berlin. Customers include university and government laboratories as well as industrial companies worldwide focused on R&D and quality control.
