Abstract
A device for filling a container, such as a dispensing tip, with a powdered or liquid material, and methods of use of the device are disclosed. The device generally includes a vacuum manifold having at least one port, and a vacuum source for creating a negative pressure in the vacuum manifold. The device may further include at least one container having an axial bore therethrough, a proximal end, and a distal end which includes a stop positioned therein. The negative pressure created in the vacuum manifold by the vacuum pump is sufficient to pull the powdered or liquid material through the distal end into the axial bore of the at least one container. A clearance between an outer surface of the stop and an inner wall of the container is configured to prevent passage of the powdered or liquid material.
