BOD Sampler

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
