The U38 Sampler is designed for taking 38 mm diameter undisturbed samples by hand in cohesive soils free of gravel or granular material. These samplers are often used in hand auger holes or trial pits.
The apparatus consists of open-ended steel Sample Tubes with a chamfered cutting edge. A special Head Adaptor is required to connect the sample tubes to Extension Rods.
In soft soils, the sampler is simply pressed into the soil. In harder soils, the sample tube can be driven into the ground using a Jarring Link.
Each sample tube is provided with push-on plastic end caps.
Samples are suitable for:
- Soil fertility determinations
- Volume weight determinations
- Determination of granular composition
- Chemical analysis of soil
- Field education
