Sartorius BioWelder TC Tube Welder Unit 3 for Sterile Thermoplastic Tube Welding

The Sartorius BioWelder TC Tube Welder Unit 3 is an automated sterile welding system designed for the sterile connection of thermoplastic tubing commonly used in single-use bioprocessing and biotechnology applications. It supports tubing sizes from ¼" to 1" outer diameter (OD) and provides validated material-specific welding programs to ensure optimal weld quality for TPE and silicone tubes.

Key technical features include:

• Automated sterile welding with dry or liquid-filled tubing capability, essential for aseptic fluid pathways in upstream and downstream processes such as media transfer, sampling, and harvesting.
• Blade depyrogenation exceeding 400 °C combined with precise weld temperature control to guarantee contamination-free connections.
• Welding cycle times between 1.5 to 2.5 minutes, facilitating efficient workflow integration in biomanufacturing or molecular diagnostics pipelines.
• Touchscreen interface with weld data logging, providing traceability and documentation important for biotechnology regulatory compliance.
• Power consumption rated at 300 VA, compatible with 100-240 VAC, 50/60 Hz power inputs, supporting global laboratory environments.
• Compact, closed-system design optimized for cleanroom compatibility, minimizing contamination risks during sterile tubing joins.

Applications include:

• Creating sterile welds in single-use bioprocess systems, indispensable for biopharmaceutical production and synthetic biology research.
• Joining thermoplastic tubing during critical steps such as media or buffer transfer and closed-system sampling workflows.
• Establishing aseptic tubing connections for seed-train development and cell culture media delivery.

This unit is widely employed in biotechnology, pharmaceutical development, and clinical diagnostics laboratories requiring reproducible, validated sterile tube welding. Its robust construction and streamlined operation support routine bioprocess workflows, including gene editing and molecular cloning workflows where sterile fluid transfer integrity is critical.

Additional options include a variety of tubing holder sets customizable to specific tubing sizes. Consumables such as Tuflux® silicone and TPE tubing must be procured separately. The instrument is tested for functionality across multiple welding modes and comes with a 120-day continental US warranty and 60-day international warranty.

This tube welder supports biotechnology professionals by enabling closed, contamination-free welding in single-use bioprocessing systems, highly valued in biopharmaceutical production pipelines and molecular diagnostics setups. Its consistent weld quality and data logging capabilities make it a critical instrument for laboratories focused on maintaining aseptic conditions and regulatory compliance.
