Rotary Sample Divider to EN932-1

No matter whether in research, development or quality control laboratories, for retained or documentary samples for chemical and physical analyses or for ring tests the rotary divider is versatile in application within a reliable quality assurance system. Extremely simple to operate, it guarantees representative division even of non-homogeneous materials into representative sub-samples. By exact division of large-grain, powder or pourable bulk materials, the sample divider establishes the most important conditions for precise analysis results.

The rotating divider divides the sample so exactly that the composition of each fraction of the sample corresponds exactly to that of the original bulk sample. This procedure guarantees a very high degree of dividing accuracy and reproducibility with both fine and coarse materials.

The material feed and dividing processes take place automatically, without interruption and without loss of material. The feed amount can be from a few grams up to 8000ml depending on the collection vessels used. The maximum feed amount corresponds to the total capacity of the collection vessels used. It is possible to produce an individual number of identical fractions for various applications by the repeated division or combination of fractions.

The material to be divided first flows through a decentrally located feed hopper directly into the openings in the dividing head.Even with coarse material, this achieves a very low level of deviations between the materials in the sample flasks. The dividing process itself runs automatically and without manipulation.
The dividing head rotates ¨C with speed monitoring ¨C at a constant
110revolutions per minute, independently of the load and the mains frequency. In specific terms that means that with a dividing head with ten outlets, the feed flow is divided into 1100 individual samples
each minute. An optimal dividing accuracy is thus guaranteed. The dividing heads divide the material evenly among the sample vessels. Both wide neck and Duran laboratory flasks are available, depending on the quantity and further application.
