    3.Advantages
    • Complete size specifications, with inner diameter from 1/8'' to 1''

    • Working temperature range: -40℃ - 135

    • Animal derived component free (ADCF)

    • Sterilization by autoclave or gamma irradiation

    • Excellent aseptic welding & sealing performance: I-Flex thermoplastic tube itself features excellent heat welding performance and can be welded with tubes from other suppliers. After welding, the tube interface is smooth, with qualified pressure resistance and sealing performance.

    • In different environments, I-Flex thermoplastic tubes can be aseptically disconnected after heat sealing, and the tubes after heat sealing are flat and free of air bubbles, with qualified pressure resistance and excellent heat-sealing performance.

    • Complies with relevant regulations of RoHS, REACH and MSDS

    • Documents of extractables study and validation are available on-demand
