PureWeld XL tubing is designed for high purity and secure peristaltic pumping. A high-quality weldable tube capable of completely secure welding, PureWeld XL allows for connector-free fluid paths to be assembled in just minutes. PureWeld XL has been developed in our state-of-the-art extrusion facility followed with extensive testing inside our peristaltic pumps. Test results show that PureWeld allows for the least internal spallation when compared to other weldable tubing, allowing the tube to remain pristine and outlast other brands, making it more economical than alternative products. PureWeld XL is a thermoplastic elastomer tubing and contains no animal-derived components that could leach into precious duty fluids. With a high level of purity and clarity, PureWeld XL is ideal 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. PureWeld XL meets full bio-pharmaceutical testing standards including FDA requirements and USP Class VI certification.
