This is a 65 pound (29.5 kg) sampler for suspension by cable, reel and crane to take larger suspended sediment or water quality samples. Originally designed to take samples in streams that are below freezing, it has mainly been used as a water quality sampler in its epoxy coated trace metal version.

The sampler has a cast bronze streamlined body which is completely open in the front to hold a 3-liter plastic container (sold separately). The section tail enables the instrument to orient into the streamflow for velocities up to 8.2 feet/sec. A plastic nozzle cap screws onto the sample bottle and has a tapped hole to receive a 5/16 inch inside diameter nozzle. An opening in the nozzle cap is provided to allow air escape as it is displaced by the sample being collected in the container.

Each sampler is furnished with one D-77 nozzle cap and two nozzles. Shipment is made in a hinged wooden box suitable for storing and transporting. The D-77-A1 TEF cap is sold separately.

The sampler is also available in an aluminum cast body for use with velocities up to 4.3 feet/sec. and is designated as the US D-77AL. The D-77AL weighs 25 lbs. The samplers can be supplied with an epoxy coating for trace metal sampling.
