Tube Welders

Tubing welders provide alternative methods for aseptic connection with thermoplastic elastomeric tubing. They are useful for connecting tubing between sterile containers, bioreactor bags, and process equipment.  Tubing welders use heated, replaceable blades to permanently connect two separated tubing together while maintain sterility of the path. Several tube welders on the market can weld TPE tubing of various types and sizes with short cycle times (min.). Easy to use, ability to weld wet, dry and/or filled tubing, user friendly interface, and validation requirements are some of the key factors to consider when choose a welder for targeted bioprocess application.

Below items are some examples of commonly used commercial products, more detailed product information can be found at supplier’s website by click links through texts.
