At analytica 2026, Siemens presented the results of the world’s first independent comparative study on laboratory ventilation systems in the life science sector. The PEARL study provides comparable data under real load conditions for the first time and enables direct application in the planning, optimization and operation of laboratories worldwide.

The study was carried out between November 2024 and February 2025 together with H. Lüdi + Co. AG and the Lucerne University of Applied Sciences and Arts as an independent testing institute. Three different air supply systems in seven configurations were controlled under controlled conditions and loaded to their limits. The focus was on comparing safety, contamination control, user comfort, system flexibility, adaptability and ventilation efficiency.

The results show that precise volume flow control is crucial. An oversupply of air impairs controlled conditions and leads to higher costs and higher CO₂ emissions. In some scenarios, less than half of the usual air volume was sufficient. As a result, ventilation efficiency increased by 45 percent, and hazardous gases and heat were better dissipated. In addition, the recovery time after a simulated spill was reduced by up to 29 percent, which significantly improves user safety and comfort.

Siemens is further developing the Smart Lab Ecosystem to make the laboratories of the future safer, more adaptable and more sustainable. The results of the study are intended to serve planners and operators worldwide as a basis for optimised ventilation concepts.
