Smaller vessels, as well as larger vessels which require 100+ samples/cycle, present a new set of problems when it comes to retrieving a representative sample. In comparison to more "standard" sampling scenarios, there are either too few or no appropriate ports such as sanitary connectors, ingold, or NA. As such, the technician must employ some ingenuity to the situation. Most Bench-Top vessels (1 liter - 15 liters) have a standard set of ports welded into the lid of the vessel. One of these is a barbed spike connected to a dip tube which extends into the vessel cavity. Generally there is a length of tubing with one end sealed assembled onto the barbed connector of the vessel.

The following is an overview of how a sample is retrieved:

ASI now offers a complete line of small vessel sampling bags to compliment this procedure. As well, the patented “Pinch and Cut” separation device negates the need for an expensive tube sealing apparatus as described in the final step above.
