Sampler & Bottles
This water sampler is designed to properly
collect biological oxygen demand (BOD) water samples
for oxygen determination by Winkler titration or
test kit analysis. The 400 ml sample chamber
contains a 60 ml BOD bottle and is deployed in the
closed position to the specified depth. A sharp pull
on the towline dislodges two rubber stoppers
allowing water to flush through the BOD bottle while
air escapes through a port. The sampler is
retrieved, lid removed, and the water sample is
ready for oxygen determination. For rapid descent
and minimal drift in low currents, attach the 2 lb.
weight. The unit includes a clear polycarbonate and
polyethylene sample chamber, 2 lb. lead ballast
weight, and 60 ml bottle.
10.0 m calibrated line with 1.0 m graduations,
and carrying case are sold
BOD Sampler 7 lbs.
