Rotary Sample Divider, Rotary Splitter, Spinning Riffer

Rotary sample divider is a type of laboratory sample splitter or sample divider. HMK-2001 Rotary Sample Splitter uses frequency controlled rotary motor and vibration-controlled device to optimize the sample dividing. It is much more superior to the traditional manual riffle sample splitter and has been widely used in lab powder analysis applications especially with particle size analyzers.
