A tip is operatively coupled to the pipette dispenser. The tip includes an electromechanical print head to dispense the volume from the pipette dispenser to the dispensing location based on a command from the pipette dispenser that indicates an amount of the volume to be dispensed from the print head. ## Claims ### Claim 1 An apparatus, comprising: a pipette dispenser to control dispensing of a volume to a dispensing location; and a tip that is operatively coupled to the pipette dispenser, the tip includes an electromechanical print head to dispense the volume from the pipette dispenser to the dispensing location based on a command from the pipette dispenser that indicates an amount of the volume to be dispensed from the print head. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the tip receives the volume from another collection source than the pipette dispenser and the tip is operatively coupled to the pipette dispenser to dispense the amount of the volume from the print head based on the command. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the pipette dispenser further comprises a collecting tip to collect the volume, the collecting tip transferring the volume to the print head to be dispensed at the dispensing location based on the command. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the print head is at least one of a thermal ink jet print head and a piezo print head that dispenses a specified volume in response to the command. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the pipette dispenser includes a controller to generate the command to the print head to indicate the amount of the volume to be dispensed from the print head. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the controller includes a wireless connection to receive dispensing commands for the print head from a remote computing location. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the print head is employed to control the portion of the volume dispensed from the pipette dispenser based on the command such that the portion is less than a predetermined amount of the volume. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the volume is about 1.0 milliliters and the portion is controlled to a range from about 2.0 micro liters to about 0.1 nano liters by the print head. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the pipette dispenser further comprising a universal serial bus connection to provide power to the pipette dispenser. ### Claim 10 An apparatus, comprising: a pipette dispenser to dispense a volume to a dispensing location; and a tip that is operatively coupled to the pipette dispenser, the tip includes an electromechanical print head to dispense a portion of the volume to the dispensing location, the print head employed to control the portion of the volume dispensed from the pipette dispenser such that the portion is less than a predetermined amount of the volume. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the volume is about 1.0 milliliters and the portion is controlled to a range from about 2.0 micro liters to about 0.1 nano liters by the print head. ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the tip receives the volume from another collection source than the pipette dispenser and the tip is mated to the pipette dispenser to dispense the amount of the volume from the print head based on the command. ### Claim 13 (depends on 10) The apparatus of claim 10, wherein the pipette dispenser further comprising a collecting tip to collect the volume, the collecting tip transfers the volume to the print head to be dispensed at the dispensing location based on the command. ### Claim 14 A system, comprising: a pipette dispenser to control dispensing of a volume to a dispensing location; a controller in the pipette dispenser to specify a command based on an amount of the volume to be dispensed to the dispensing location; and a tip that is operatively coupled to the pipette dispenser, the tip includes an electromechanical print head to dispense the volume to the dispensing location based on the command from the controller that indicates an amount of the volume to be dispensed from the print head. ### Claim 15 (depends on 14) The system of claim 14, wherein the print head is to control the portion of the volume dispensed from the pipette dispenser based on the command such that the portion is less than a predetermined amount of the volume, the volume is about 1.0 milliliters and the portion is restricted to a range from about 2.0 micro liters to about 0.1 nano liters by the print head.
