Product Overview
Micro Pumps
Lee Company highly reliable fixed and variable volume dispense pumps are ideal for positive fluid displacement applications in diagnostics, including reagent dispensing, aliquoting, probe washing, and sample preparation. Their ultra-fine resolution enables high precision volumetric aspirating and dispensing with exceptional accuracy. These pumps are maintenance-free and have an extensive life, so you can minimize downtime and position the pump where the system’s fluidics dictate, regardless of accessibility.

Fixed Volume Pump
The Lee fixed volume dispense pump is a solenoid-driven, chemically inert positive displacement pump which provide accurate and repeatable dispense volumes ranging from 25 to 50 µL in a small, lightweight package. The fixed volume pump requires a simple electrical signal for operation. The pump aspirates fluid when energized and dispenses fluid when de-energized. Integrated check valves, together with our unique housing design and diaphragm seal interface, prevent siphoning when the dispense point is positioned above the fluid reservoir.

Disc Pump (Latest)
Lee Company disc pumps are highly precise pneumatic micropumps that generate pressure or vacuum in a small (29 mm), silent, vibration-free form factor. Their infinite turndown ratio and pulsation-free flow allow control over gases or liquids (indirectly) with incredibly fine resolution, enabling a multitude of innovative applications. They are available with or without electronics for added simplicity and are ideal for providing pressure-driven flow using the air over liquid method as well as for pipetting, aspirating, dispensing, droplet generation, and numerous other microfluidic applications
- Silent operation <10dB
- Small size and light weight,
- Weight approx. 5g, size Dia 29.4 x 11mm
- Exceptional pressure depending on model as low as – 400mbar, as high as 600mbar.
- Flow up to 2.0 L/min
- Ultra-fast (ms) response to set-point changes
- Full control flexibility
- Evaluation and development kit are available for quick prototyping and testing
- Smart Pump Module (with integrated drive electronic and pressure sensor) is also available.
- Full range of available flow and pressure options
