ABSTRACT:
An apparatus, system, and process for making a sterile connection between two thermoplastic resin tubes is disclosed. The tubes are cut by a hot cutting means so as to form a molten interface between the tubes and the cutting means. The tubes are aligned with each other and slid off an edge of the cutting means while being urged together. As the thermoplastic resin cools a sterile splice is formed. The apparatus is controlled to provide precise timing of the above events and includes safeguards to ensure sterility is maintained.
