Big inputs and accurate outputs for seriously reliable results.
- The Rocklabs Standalone RSD (Rotating Sample Divider) is designed to split out a representative portion of the sample with a proportion of 2-50%.
- Featuring sealed bearings the Standalone RSD has two splitting options available. The first is a single split & remainder. The second option is a duplicate split & remainder, with a bypass bin available for option two.
- Taking a representative split 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.
Benefits:
- Robust design
- Easy operation
- Dust extraction port
- Two splitting options

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.
* Critical evaluation of powder sample procedures. Allen T and Khan A. A, The chemical Engineer, May 1979, pp108 - 112 |
