Watson-Marlow’s PureWeld XL weldable tube is designed for high-purity and secure peristaltic pumping. Secure welding allows the tube to provide connector-free fluid paths in minutes. Test results show the tube has the least internal spallation compared to other weldable tubing, making it long-lasting and economical. The thermoplastic elastomer tubing contains no animal-derived components that could leach into precious-duty fluids. With a high level of purity and clarity, it is a good fit for use in sanitary environments in pharmaceutical and biotechnology processing applications, from research to production, including cell media and fermentation, sterile filling and dispensing, high-purity water transfer, vaccine production, fluid transfer, and filtration. The tube meets full biopharmaceutical testing standards including FDA requirements and USP Class VI certification. – watson-marlow.com
