Sample preparation for soil analysis. The Sample Mate™ 600 (Mortar Grinder) grinds and mixes soil and rubble samples in one process cycle, tackling any hard components in the sample with ease. The Sample Mate™ 600 (Mortar Grinder) grinds and mixes soil and rubble samples in one process cycle, tackling any hard components in the sample with ease. Once this pre-treatment step is complete, the sample is ready for physical and chemical analyses. As samples are inconsistent in texture, any impurities are usually distributed unevenly through the sample. Sub-samples are therefore not representative of the whole sample. To ensure that the required national and international standards are met, an additional pre-treatment step is necessary. This step not only takes extra time and costs more money, but it also renders urgent analyses with turnaround times of less than 24 hours completely impossible. But with the SampleMate™ 600, this concern becomes a thing of the past.
