About

Roland Weibel is a leading expert in the engineering of liquid-handling systems, with a focused research program on the critical challenge of carryover contamination in automated clinical diagnostics. His work addresses a fundamental tension in laboratory automation: the trade-off between the speed and cost-efficiency of fixed, reusable pipetting tips versus the contamination risk they pose compared to disposable alternatives. Weibel’s major contributions include the development of the first standardized test procedures for quantifying carryover from fixed tips, providing a rigorous, reproducible framework for evaluating system performance. He further advanced the field by demonstrating an integrated decontamination step within the washing procedure that significantly reduces carryover, effectively bridging the gap between reusable and disposable tip reliability. While his most-cited works (11 and 6 citations respectively) are highly specialized, their impact is profound within the niche of in vitro diagnostics and open-platform robotics, where they serve as foundational protocols for quality assurance. Weibel’s achievements lie in transforming a persistent, practical problem into a measurable, solvable engineering challenge, directly improving the accuracy and reliability of high-throughput clinical analyzers used in laboratories worldwide.
