Method for dispensing liquid utilizing flow of liquid

Abstract

A method for accurately and precisely aspirating and dispensing liquid from a in the nano-liter range without contacting the syringe tip to the target reservoir during dispensing. Such a method utilizes a partially collapsible syringe tip that compresses when subjected to pressurized fluid around its outer surface area to discharge a liquid at the tip of said partially collapsible syringe tip with a high velocity. Such a discharge of liquid at such a high speed allows even the smallest amount of liquid in the nano-liter range to be dispensed to a target reservoir without contacting the target reservoir.

         10 . A method of dispensing a liquid comprising:
 enclosing a portion of a partially collapsible syringe tip in a fluid chamber;   opening a set of valves juxtaposed at both sides of said fluid chamber controlling a flow of fluid into said fluid tight chamber;   allowing said flow of fluid into said fluid chamber;   wherein said flow of fluid exerts a force on said partially collapsible syringe tip to dispense said liquid.   
     
     
         11 . The method of  claim 10 , wherein said partially collapsible syringe tip is further comprising:
 a first rigid portion at a proximal end of said partially collapsible syringe tip;   a second rigid portion at a distal end of said partially collapsible syringe tip to dispense said liquid; and   a collapsible portion connectively placed between said first rigid portion and said second rigid portion adapted to be enclosed by said fluid chamber.   
     
     
         12 . The method of  claim 11 , wherein said fluid chamber encloses said collapsible portion of said partially collapsible syringe tip. 
     
     
         13 . The method of  claim 12 , wherein said fluid chamber is capable of enclosing a plurality of partially collapsible syringe tips. 
     
     
         14 . The method of  claim 13 , further comprising:
 connecting a plurality of fluid chambers to said valves to create a plurality of fluid chambers.
