Abstract
Apparatus and Method for Handling Fluids at Nano-Scale Rates. A linear displacement pump produces non-pulsatile liquid flow rates as low as the nl/mm range. The pump includes a servo motor, a gear reduction, a lead screw, a linear stage, a barrel, and a plunger extending into the barrel and coupled to the stage. A microfluidic interconnect device can be coupled to the barrel. One or more of these pumps can be disposed in a thermally controlled pump assembly that includes a pump housing, a thermally conductive body disposed in the housing and including first and second opposing sides, and a temperature regulating element such as a thermoelectric device disposed in thermal contact with the thermally conductive body on a side thereof opposite to the barrel or barrels of the pumps.
