D-96 Sediment Sampler

The US D-96 is a collapsible-bag suspended-sediment/water-quality sampler capable of collecting a 3-liter sample. It is 35 in long, weighs 132 lbs, and has a hollow cavity inside the sampler body. It is fabricated from bronze and aluminum castings with a high-density polyethylene tail. All metal parts are plastic coated. The sampler employs a sliding tray that supports the bag and holds the nozzle holder with nozzle in place. The bag is attached to the nozzle holder with a hook-and-loop strap. The sampler uses a plastic or TFE nozzle and a plastic or PFA bag as the sample container. The US D-96 meets the protocol for water-quality sampling as outlined in the USGS’s National Field Manual for the Collection of Water-Quality Data.

The US D-96 sampler will collect acceptable flow-weighted samples in streams velocities ranging from 2.0 to 12.5 ft/sec. Extreme care should be practiced when deploying the sampler at stream velocities above 10 ft/sec. The US D-96 sampler is capable of sampling to a depth of 39 ft with a 5/16-in internal diameter nozzle, 60 ft with a 1/4 in internal diameter nozzle, and 110 ft with a 3/16-in internal diameter nozzle. The unsampled zone using the US D-96 sampler 4 in.
