ABSTRACT:
A process, apparatus and system for making a sterile connection between two thermoplastic resin tubes is disclosed. Side sections of the adjacently placed tubes are melted by passing a heated elongated body therethrough to form a molten seal between a surface of the heated body and the adjacent side sections, thereby providing a seal between the interior and exterior of said tubes. The resulting molten tube sections are urged together as they are slid off an end of the elongated body. As the thermoplastic resin cools a sterile weld is formed.
