20. A micro-valve system comprising:
a first capillary and a second capillary symmetrically positioned in between a first and second support towers and having a space between a first end of the first capillary and a first end of the second capillary;
the first end of the first capillary being connected to a first end of a sleeve connector;
the first end of the second capillary connected to a second end of the sleeve connector;
the second end of the first capillary being supported by the first support tower; and
a compressing system positioned adjacent the sleeve connector, the compressing system configured to compress the sleeve connector to block fluid flow between the first capillary and the second capillary,
wherein the sleeve connector is formed of a flexible material and
wherein the compressing system comprises a pair of poles, the poles being positioned on either side of the connector sleeve, a motorized system operated by a computer moves the poles toward and away from the connector sleeve, the poles contacting the connector sleeve to provide a compressing force to block fluid flow between the first capillary and the second capillary.
