Rocklabs Standalone RSD

The Rocklabs Standalone RSD (Rotating Sample Divider) is designed to split out a representative portion of the sample with a proportion of 2-50%.

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
• 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. * Critical evaluation of powder sample procedures. Allen T and Khan A.
