5. Product Overview
The BVS4300 and CVS4200 Stationary Samplers are automatic liquid
samplers for water and wastewater applications. CVS/BVS Samplers are
capable of gathering fluid automatically from a variety of sources, including
containers, open channels, sewers, pipes, and any open source of water.
Samplers are designed for reliable, unattended sample collection. Refrigerated
units will keep the temperature of the deposited liquid at 4ºC (39.2ºF) until the
samples are gathered and brought back to the laboratory for analysis.
There are a variety of methods for depositing samples. Composite sampling is
used where samples are deposited, over time, into one container. Discrete
systems are used when multiple bottles are needed. These are also called
“sequential” systems, and involve a stepper with distributor arm which
dispenses the liquid into a bottle, then moves to the next bottle.
