ABSTRACT:
A process, apparatus and system for making a sterile connection between two thermoplastic resin tubes is disclosed. A hot stream of fluid is urged either through both said tubes transversely of the axis of each tube or through opposing side sections of the tubes substantially perpendicular to the axes of the tubes to form continuous contact between the hot fluid stream, the interior of the tubes and molten tube portions thereby formed. The tubes are aligned with each other, if necessary, and urged together while the hot fluid stream is removed. As the thermoplastic resin cools a sterile weld is formed.
