An apparatus for taking an intestinal sample of a human or animal patient comprises a holder part and an expandable part supported by the holder part and having one or more sampling areas on the surface thereof. The system includes means for identifying and recording the identity of the dispensing vehicle, the dispensing operator, the location of the dispensing vehicle, the receiving vehicle, the receiving port on the receiving vehicle, the type of fluid dispensed, the quantity of fluid dispensed, and the time of the dispensing. The address is used to access a CC associated with a previous packet for the same PID in a random access memory. Preferably, the connections between the secondary uprights and the secondary front-rear stretchers are adjustable so that the secondary uprights can be secured in different positions within the warehouse-type rack.
