By Chemical Engineering |

This miniature, chemically inert stepper dispenser pump (photo) is designed to deliver variable micro-liter volumes (50–250µL) with a consistent performance. The LPD Series pump has been developed to offer greater design flexibility and significant cost savings to the medical and scientific industries as a result of its maintenance-free design. It can be located wherever fluidic requirements dictate, regardless of maintenance accessibility. The pump is offered in both standard and high-performance models, with the latter incorporating a home sensor, encoder and backlash compensation for more demanding applications, and provides a CV of ≤0.01% at total volume. The standard performance model is available with a home sensor for most other applications. Maximum discharge pressures are 60 psi. — Lee Products Ltd, Gerrards Cross, U.K.
