Lilian Labs GmbH
About
Lilian Labs GmbH, founded in 2016 and based in Braunschweig, Germany, develops and manufactures the LILIAN Water Analysis System, a mobile photometric instrument for digital water quality measurement. The company was established by three physicists and engineers from TU Braunschweig, the University of Gottingen, and the Fraunhofer Institute: Dr. Sebastian Doring (Production), Dr.-Ing. Alexander Rohr (Marketing and Sales), and Dr.-Ing. Torsten Rabe (Development). The company name stands for Liquid Light Analytics, reflecting its spectroscopic measurement approach. The LILIAN system uses proprietary disposable SensoStick cartridges that integrate pre-measured reagents, eliminating chemical mixing and reducing analysis time by up to 90 percent. The one-button handheld device features automatic calibration and Bluetooth smartphone connectivity, delivering results in under 60 seconds. Available SensoStick cartridges include Pool Cl (pH, free chlorine, total chlorine), Pool Cl HR (high-range chlorine), Bromine (free and total bromine), Chlorine Dioxide, Acid Capacity (total alkalinity), and CYA (cyanuric acid). The LILIAN Manager cloud platform provides real-time dashboard monitoring, automatic limit-value alerts, and full traceability of measurements. An API interface enables integration with external data management systems. All devices are developed and manufactured in Braunschweig, and the company operates a SensoStick recycling take-back program. Primary markets include public swimming pools, hotels, and private pool operators.
