ABSTRACT:
A liquid sampling device is provided for periodic aseptic removal of samples of a source liquid to be analyzed, comprised of a primary liquid conduit tube closed at one end and, at the other end, adapted to be in liquid communication with a principal or secondary flow line through which the source liquid flows or is arranged to flow, and a plurality of separate sample conduit tubes emanating from and in liquid communication with the primary liquid conduit tube, one end of each sample conduit tube being adapted to withdraw therethrough a sample of the source liquid. The device is configured such that, after a sample is taken through a particular sample conduit tube, that tube can be isolated or removed from the system, and subsequent samples are taken successively from remaining sample conduit tubes in the same manner.
