Abstract
A dispense tip for low-volume dispensing is formed according to a process. The process comprises forming a hole through a length of a neck formed of a body of material; forming an inlet hole at a distal end of the hole, the inlet hole having a first inner diameter; forming an outlet hole at a distal end of the inlet hole, the outlet hole having a second inner diameter less than the first inner diameter, a first inner taper transitioning the inlet hole from the first inner diameter to the second inner diameter; forming an outer taper having a width that decreases along a longitudinal axis of the length of the hole in a direction of a distalmost end of the outlet hole; and reducing a width of an opening at the distalmost end of the outlet hole to a third inner diameter that is less than the second inner diameter.

A dispense tip for low-volume dispensing formed according to a process, comprising:
- forming a hole through a length of a neck formed of a body of material;
- forming an inlet hole at a distal end of the hole, the inlet hole having a first inner diameter;
- forming an outlet hole at a distal end of the inlet hole, the outlet hole having a second inner diameter less than the first inner diameter, a first inner taper transitioning the inlet hole from the first inner diameter to the second inner diameter;
- forming an outer taper having a width that decreases along a longitudinal axis of the length of the hole in a direction of a distalmost end of the outlet hole to a distalmost end of the neck;
- and
- reducing a width of an opening at the distalmost end of the outlet hole to a third inner diameter that is less than the second inner diameter, wherein the distalmost end of the neck and the distalmost end of the outlet hole are positioned along a common horizontal plane.
