Abstract: An apparatus for attaching a tube segment to a bag by fusing them together in an aseptic form, fill and seal operation is provided. The apparatus includes a sterile processing chamber in which a sterilized tube segment and a pair of opposing wall portions of a flexible bag are to be located. The sterilized tube segment has an open end which is to be placed in communication with an interior space of the bag. A tube inserter is at least partially located within the processing chamber and arranged to grip the tube segment and place the tube segment between the wall portions of the bag. At least one member is provided for fusing the tube segment between the wall portions of the bag so that the open end of the tube segment is in communication with the interior space in the bag. A bag formed using the apparatus and a method of forming the fused tube-on-bag are also provided.

Abstract: A current probe calibration fixture in which a pair of conductors of constant dimensions are constructed to surround the coils of the probe and to be spaced from the conductive shield around the coils by a dielectric of constant dimensions so as to assure a uniform desired impedance between the two conductors and minimize excessive currents.
