An apparatus and method for controlling the flow of molten material from a melt container. Each time the router receives a DHCP request or discover packet, the router checks to see if the packet is already in the cache. The graft syringe assembly further comprises a connection subassembly coupled to the syringe adapter, and a delivery tube subassembly coupled to the connection subassembly, wherein the connection subassembly is configured to allow the delivery tube subassembly to rotate relative to the syringe subassembly. The invention includes a capillary tube where two or more than two polymer groups are covalently bonded to each other by a cross-linker. The flow director has a height increasing in a direction from the leading end towards the trailing end. The neck support has a generally U-shaped configuration defined by opposed free ends.
