Prospective fields of application for electrokinetic capillary micropump

- medicine (regulated delivery of insulin and other drugs);

- chemistry and biology (lab-ware for micro-dozing, micr0-fluidic systems, lab-on chips

Micropump Designed

for feeding at the level from micro to nano liters in a minute 

Micropump based

on using electro-kinetic effects related to the formation of double electric layers on a phase boundary between polar liquid and solid dielectrics.

New constructive

Charges, under the influence of a field, move and carrying away a liquid behind itself

Micropump Properties

Distinctive properties of the IRO capillary electrokinetic micropump

(priority date from 07.07.2005):

-  no electrolyzing processes with gas bubbling which blocks work operation or makes it unstable;

- opportunity for fine regulation of fluids from tens nano-liters up to milliliters per minute by changing voltage only;

- compactness of device, durability owing to absence of moving mechanical parts. 

Pressure at micropump outlet depending on diameter of single channel and voltage.

Flow rates of NaCl solutions of different concentrations depending on voltage. Channel – 10 microns, amount of channels – 360 000.
