Sand / Silt Dredge

The Sand / Silt Dredge is made entirely from 300 series stainless steel. It features a hinged scissor jaw design with a trigger mechanism that olds the sampler open until it contacts the surface to be sampled. Raising the dredge closes the scissor jaws to collect the sample. Comprised of all stainless steel, it weighs just 5 lbs and has 6" x 7 1/2" jaw opening.

Dredge Applications

A bottom sampling dredge consists of two halves of a relatively small box. The dredge is placed onto the bottom sediment, then closed and pulled up to retrieve a sample. A two-way mechanism prevents accidental closure while the dredge is dropping. The impact of the dredge on the bottom surface triggers the spring-loaded release mechanism without using a messenger. After mechanism closure, the dredge is pulled up to retrieve the sample.

Careful release of the sample distributes the sample approximately as it appeared on the bottom, making sediment profile description possible. The sample is not suitable for most geotechnical analysis and does not provide samples suitable for high-quality chemical analysis for volatile contaminants.
