Stops caving sediment!
Use this manually-driven sampler for discrete interval sediment sampling in rivers, lakes, wetlands, and estuaries. To obtain a sample, the sampler is lowered to the surface as a dual tube or driven down to the desired depth where sampling is to begin below the surface. Upon reaching the desired sampling depth, the inner rods attached to the internal drive tip are retracted and removed, and additional extensions are added. Then, the internal drive tip is released and retained in a chamber at the top of the sampler. Next, the slide hammer is attached, and the sampler is driven down to collect the sample. Once the sample has been collected, the rods and sampler are back-hammered out of the bore hole. If sampling in harder or tighter sediments, the rods and sampler can be jacked out of the sample boring using the optional removal jack and pull cap. After removal, the sampler disassembles easily to allow access to the sample liners which can then be capped off for transport to the lab.
Two (2) o-rings are used on the internal drive tip to minimize the chance of cross-contamination
Core catcher helps prevent the loss of the sediment sample
The sampler can take continuous or discrete samples from the sediment surface to 4' in depth
