Fidelity & Precision
How do we ensure that our products are quality-built? By building them ourselves—from the ground up. We design, manufacture, and assemble over 90% of our instruments in-house, including most of the critical components and parts. This level of vertical integration means we control quality at every stage, from raw materials to the finished instrument in your lab.
For the small percentage sourced externally, we apply the same rigorous scrutiny, ensuring every part and instrument meets our commitment to excellence, because the instruments in your lab make a difference in your work. At LECO, quality isn’t outsourced—it’s engineered into every part, every component, every instrument.
