This stepper motor-driven positive displacement pump provides unparalleled reliability and performance at an economical price. With this variable volume pump, you can aspirate an accurate volume of fluid and dispense that fluid volume out in smaller, highly precise increments. Standard models are available with full dispense volumes of 50, 250, 1000, and 3000 µL, and with ¼-28 ports in either a PEEK or PMMA (acrylic) port head. Featuring a flexible and maintenance-free design, it can be positioned in the ideal fluidic location within a system, regardless of accessibility. All designs are equipped with a home sensor to establish end of stroke. High performance models are offered with integrated backlash compensation and an optical motor encoder to provide feedback on piston movement. Each pump is 100% tested to guarantee performance. Customization options are available.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
