We’re L&R, the worldwide leader in the manufacturing and distribution of Ultrasonic Cleaning systems, solutions, and accessories. Our reputation for quality products, as well as our ongoing commitment to extensive research and development, have been the driving force for over 90 years.

Founded in 1930, Max A. Lazarus Sr, a printer by trade, formulated specialty cleaning and rinsing solutions to clean mechanical watch and clock parts. Soon after, he created specialty products for the cleaning of gold, diamonds, precious metals, and stones.

Along with a full line of ultrasonic cleaning solutions for cleaning instruments, dentures, and apparatus, we became the trusted name and leader in instrument care and cleaning, establishing a worldwide distribution network.

Today, L&R’s core markets also include the industrial, scientific, and law enforcement/ military industries in addition to niche markets around the world. While our reach is global, we remain accessible and personally involved with all our customers. At L&R, clean matters and so do our customers.
