A distributor tube is pre-installed in the 630112 and 630113 distributor arms. This tube connects to the peristaltic pump.
If the ProSample is being used for composite sampling (i.e. a single, large bottle is installed), the distributor tube can be used as a replacement composite tube, although the user may want to cut it to the appropriate length.
Please see the ProSample Ordering Guide if ordering a complete system, or contact us if you have any questions.
