These closures enhance container functionality by incorporating tubing into the cap, ensuring reliable and efficient aseptic fluid handling. This adaptable platform allows you to customize the number, size, and material of the tubes in the cap, creating a system tailored to your specific process applications. VentiPortTM is a one-piece closure system featuring tubing ports and a specially designed gas exchange system. The gas exchange system facilitates essential passive gas exchange in an incubator, due to its large filter surface area that allows unrestricted gas flow. The compact design also leaves space in the cap for tubing ports to allow seamless aseptic fluid transfer. VentiPortTM is designed to minimize waste, eliminate contamination risks, and streamline operations.
