  • Publication number: 20170218320
    Abstract: The present invention provides a system for the insertion of a pre-sterilized sensor probe into a sterile vessel. The system of the invention provides a reliable and straightforward way to insert one or more sterile probes into a sterile vessel. The present invention also provides a sterile vessel that includes one or more of the systems of the invention. The sterile vessel can be a flexible or semi-rigid bag or tubing of the type typically used for carrying out biochemical and/or biological processes and/or manipulating liquids and other products of such processes. Furthermore, the present invention provides a method for aseptically inserting a probe into a sterile vessel where the method makes use of the system of the invention.
