Rocklabs Benchtop RSD

The Rocklabs Benchtop RSD (Rotating Sample Divider) is designed to be placed on a work bench and can be used in conjunction with Benchtop Ring Mill.

Big inputs and accurate outputs for seriously reliable results.

The Rocklabs Benchtop RSD (Rotating Sample Divider) is designed to be placed on a work bench and can be used in conjunction with Benchtop Ring Mill.
Featuring sealed bearings the Benchtop RSD takes a representative split of any proportion from 2-50%. Get a representative split of sample and remainder.
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
Sealed bearings
Two representative splits
Compact to sit on work bench

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.
