Rocklabs Standalone RSD
Rocklabs Rotating Sample Dividers (RSDs) are designed to split out a representative proportion of a sample with a high degree of dividing accuracy. The design is robust and the machinery easy to operate.
Rocklabs produce RSDs in a small bench top model and a standalone model. The Standalone RSD is designed to split out a representative portion of the sample – from 2% to 50%.
- Accurate representative split of any proportion (from 2% to 50%)
- Two splitting options available
- Sealed bearings

Comments on taking a representative split | Taking a representative split from a large sample is not as simple as many people believe. Rolling on a mat, multiple grabs or riffle splitting do not produce accurate results. A classic study* conducted at Bradford University demonstrated that a rotating sample divider provided the best results. | |
