Stechset für chemische Untersuchungen

With our special coring kit, volatilisation and oxidation of components in soil samples can be prevented as much as possible. This is due to the fact that during sampling, the sample is pushed into the sample tube, after which the tube is shut off. This will optimally prevent volatilisation and oxidation of the soil sample. So the sample under no condition comes in touch with synthetic material. This method meets the NEN 5743 norm (soil or sediment sampling with volatile components). You can also combine it with the methanol method.

The sample has a volume of 226 millilitres. The set therefore also is suitable for the determination of volume percentages of humidity in samples from undisturbed soil. With this set it is possible to take samples to a depth of more than 5 metres.

The samples are taken with a small coring apparatus fitted with thin-walled stainless steel sample tubes. The sampling tubes are preferably pushed into the soil by hand, but a steel hammer with nylon heads can also be used.

After taking the sample, the sample tubes can be locked and cooled for transport to the laboratory. Here sub-samples can be taken from the sample tube, applying a small gauge or apple-corer. The samples can also be removed using an extruder. All the parts, except the caps, can be decontaminated over and over. After decontamination the equipment can be used again. Please note that this set is not suitable for stony soils.
