Tubing Welder

Tubing welders are precision-engineered, automated devices designed to create sterile, leak-proof connections between thermoplastic tubing in bioprocessing and cell therapy workflows. These systems enable closed-system fluid transfer, eliminating the need for laminar flow hoods or manual aseptic techniques and significantly reducing contamination risks during media addition, cell harvesting, sampling, and product transfer. Tubing welders are essential in modern single-use bioprocessing platforms, especially in GMP-compliant environments where sterility, traceability, and process integrity are paramount. Widely used in biopharmaceutical manufacturing, gene therapy, vaccine production, and cell therapy, tubing welders allow operators to join sterile tubing sets without compromising system integrity, even between two closed, pre-sterilized fluid paths. They employ controlled heat and pressure to simultaneously cut and weld thermoplastic tubing—typically made from thermoplastic elastomers (TPE)—forming a seamless, sterile bond in under a minute. Once welded, the tubing functions as a continuous, leak-free conduit for fluid transfer. Compatible with various tubing sizes, wall thicknesses, and brands, tubing welders are often integrated into single-use bag systems, bioreactors, manifolds, and perfusion setups. Many models feature touchscreen controls, automated calibration, barcode tracking, and audit trails, making them well-suited for regulated production environments. Portable and benchtop versions offer flexibility for both small laboratories and large manufacturing facilities. By enabling on-demand sterile connections, tubing welders streamline single-use workflows, minimize downtime, and support lean, modular manufacturing. They also reduce the need for spare tubing lengths or additional sterile connectors, simplifying inventory management and process validation. At Wasteless Bio, we offer surplus and gently used tubing welders from trusted manufacturers. Each listing includes specifications such as tubing compatibility, weld cycle time, power requirements, sterility assurance, and regulatory compliance (e.g., GMP, ISO 13485). Sourcing tubing welders through Wasteless Bio helps laboratories reduce capital expenses while supporting sustainable, closed-system bioprocessing with high sterility and reliability.
