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.
