Watson-Marlow PureWeld XL Weldable Biopharmaceutical Tubing

Secure - no spallation up to 48 hours running. Secure welds, connector free

Ideal for: Single-use bioprocessing systems

Designed for secure peristaltic pumping, this pure thermoplastic elastomer can be welded, allowing complete fluid paths to be assembled in minutes without connectors.

The Pure Weldable Pump Tube

Watson-Marlow PureWeld XL is manufactured by the world’s leading peristaltic pump manufacturer. A high quality tubing, PureWeld XL is ideal for use in single-use bioprocessing, has very low internal spallation in peristaltic pumps, as well as long life when compared to other weldable tubes.
