The rigid stainless steel inflow and outflow tubes are connected to flexible silicone tubing (not included) with a 1/4" ID. The silicone tubing leads from the chamber to the point of sampling (e.g., on land, a pier, a boat, etc.) Sampling is accomplished by leading one tube into a peristaltic pump head (not included) to pump fluid into the chamber or aspirate fluid from the chamber. You can easily raise or lower the height of the stainless steel tubes penetrating the chamber by adjusting the watertight fittings.
The CF/RS System can be used for remote sampling as well as for isotope labeling experiments where continuous flow through the chamber is required. Sampling at periodic intervals is accomplished simply by turning on the pump as needed; for continuous flow studies, the pump may be kept running continuously.
When the CF/RS System is not being used, you can switch back to the standard sampling configuration by simply unscrewing the watertight fittings along with the stainless steel tubes and sealing off the penetrations in the headplate with nickel-plated brass caps provided with the Aquos BC-8.
