Miniature pump delivers micro-litre volumes

Miniature pump delivers micro-litre volumes

A miniature, chemically inert stepper dispense pump delivers variable micro-litre volumes in the 50µL to 250µL range. Lee Products’s LPD Series pump offers design flexibility and cost-savings to the medical and scientific industries, says the company. It can be located wherever fluidic requirements dictate, regardless of maintenance accessibility.

The pump is offered in both standard and high performance models. The latter has 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.  Discharge pressures are 60 psi maximum.

The LPD Series pump can be customised to meet specific application requirements of OEM applications and offers a long-life performance of 2 million cycles for the standard model and 5 million cycles for the high performance option.
