The Van der Horst core sampler is used for manual filling of the stainless steel sampling tubes. Sampling can take place in bore holes, casing tubes (minimum diameter 75 mm) or in the beds of canals, lakes, etc. up to a depth of approximately 10 m.
By contrast to the Akkerman core sampler the Van der Horst sampler is entered into the bore hole using extension rods.
The core sampler can be beaten into the soil using the steel hammer with nylon head or using a falling hammer (type down the hole). When the sample enters the tube, the water or air above the sample can escape through a non-return valve. After sampling the apparatus with the filled tube is extracted from the soil using the support and lever beam with rope catcher.
Among other items the standard set contains: a handle with beating head, extension rods, a steel hammer with nylon heads, a falling hammer (type down the hole), a Van der Horst core sampler, sampling tubes with and without core catcher, plastic sampling liner, sampling tubes, PE covers, a hydraulic extruder and various accessories. The complete set is delivered in an aluminium transport case.
