The Lee Company

Since 1948, The Lee Company has pioneered the development of miniature fluid control components for automated liquid handling in medical and scientific instrumentation, ink jet printing, analytical/clinical chemistry, and medical disposable applications. In response to the ever-increasing demands of the medical and scientific industries, The Lee Company’s unique capabilities in miniaturization and engineering continue to redefine miniature fluidics by integrating new and more advanced technology into smaller packages.

The Lee Company employs more than 1000 people, with state-of-the-art manufacturing facilities in Connecticut, U.S.A. and Cambridge, U.K. We have built our reputation over many decades as a preferred supplier to many major companies in the medical industry. Our worldwide network of Technical Sales Engineers is ready to work with you, engineer-to-engineer – helping you find the best components to solve your fluid control problems.

Our new line of Disc Pumps are revolutionary, ultrasonic, pneumatic piezoelectric micropumps that generate pressure or vacuum in a small, silent, vibration-free form factor. Designed for highly accurate, ultra-smooth, flow control, Disc Pump delivers unrivalled pneumatic performance and enables innovation wherever precision control of small volumes is critical.

Our Xover is a groundbreaking internal pinch-tube solenoid valve designed to switch quickly and efficiently between samples, reagents, cleaning solutions or calibrants. The Xover solenoid valve features an exceptionally low carryover volume of just 3.7 μL, and a total internal volume of just 11 µL. Xover’s innovative design combines the flow path of a pinch valve with the versatile, maintenance-free performance of a chemically inert isolation valve. Xover is ideal for critical applications in flow cytometry, gene sequencing, in vitro diagnostics, urinalysis, and hematology instruments.
