摘要: A precision fluid dispensing system containing at least one two-piece pump (1,2) and a precision closed loop controller drive system to address the small volume precision dispensing requirements of bioscience applications. A multiple diameter pump can be combined with a pump having multiple inlet (3) and outlet (4) ports to allow for precision multiple outlet dispenses in a single pump that finds use with microtiter plate pipetting and other precision dispensing. Inlet ports can be located on the smaller diameter (9) of the cylinder with outlet ports on the larger diameter (8) of the cylinder. A micro-controller with closed loop feedback provides exact linear positioning and motion of the pump piston (12) as well as optional control of a nozzle to provide exact microdispensing of fluids.

A dual piston, dual cylinder pump can be used where the upper and lower parts are different diameters and the two pistons are coupled with a fluid layer.

摘要: A method and system for controlling a rotary pump where a rotary pump can be coupled to a stepper motor, and the stepper motor can be controlled with micro- or nano- stepping accuracy using a processor controlled drive system. The processor controlled drive system moves the stepper motor according to a predetermined move profile; this causes the rotary pump to dispense a precision amount of fluid. The rotary pump can be a peristaltic pump or any other type of pump. The rotary pump can be coupled to the stepper motor through a reduction gear with a reduction ratio of 2:1 or similar. The stepper motor can be mechanically coupled to a rotational position encoder so that a measure of the rotation position can be fed back to the processor. The processor can cause the stepper motor to interpolate between pulse positions of the encoder.
