A faultless and comparable analysis is closely linked to accurate sample handling. Only a sample representative of the initial material can provide meaningful analysis results. Rotating dividers ensure the representativeness of a sample and thus the reproducibility of the analysis.
The sample divider PT 100 divides the sample so exactly that the composition of each fraction of the sample corresponds exactly to that of the original bulk sample. This applies both for fine-powdered and coarse materials. The material feed and dividing processes take place automatically, without interruption and without loss of material. The Sample Divider PT 100 has a modular design and can be put together to suit individual requirements. It offers an extremely flexible range of possible applications. A feeder, various dividing heads, sample receptacle vessels and further useful accessories are available in addition to the drive unit.

*depending on feed material and instrument configuration/settings
The material to be divided first flows through a decentrally located feed hopper The material first flows through a feed hopper - which is located off-center - directly into the openings of the dividing head. This procedure results in very small, and therefore neglectable, deviations between the part samples in the sample bottles, even with coarse materials. The dividing process itself runs automatically and tamper-proof. The speed-controlled dividing head rotates at a constant 110 revolutions per minute, independent of the load and the mains frequency. This means that when using a dividing head with ten outlets, the feed flow is divided into 1100 individual samples each minute, thus providing optimum dividing accuracy. The dividing heads divide the material evenly among the sample bottles which are available in various sizes.
