Collaborative Success Stories

“We had to think more long term at the Emerging Technologies and Innovation Center at UMass so we were pleased to discover that Lesker offered the extremely versatile Lab-Line sputter tool. We also got applications assistance which was critical to the choice. Lesker not only has provided spot on equipment and support they have offered vacuum training to our researchers that was hugely popular. No system is perfect, but Lesker has been excellent in most every phase and is anxious to improve in the areas where improvement can be made.”
