ABSTRACT:
A self contained dispensing head apparatus wherein a modified pipette tip box tray carrier is utilized to furnish pipette tips, carried in a standard pipette tip box, by a pipette tip box tray carrier to the head apparatus and wherein means are provided to engage the pipette tip box tray carrier in a manner whereby the pipette tips are loaded into corresponding internal cylinders formed in the dispense block head. The dispense block head comprises a solid block of material having a plurality of internal cylinders to engage the pipette tips in a sealing arrangement. The pipette tips are modified from the conventional design in that a disk-shaped ring portion is interposed adjacent one end of the pipette tip, a tapered end of the tip allowing a seal to be formed with the dispense block head internal cylinders.
