Spinning Riffler- Representative Sampling

Analysis and testing of powders for chemical assay and physical measurements, such as particle size, density and surface area, often requires a large sample quantity to be split into smaller amounts by, for example, spin riffling or rotary riffling. Therefore, it is necessary that the sub-sample shall be a representative sample of the initial lot or batch for reproducible and valid data.

The Rotary Micro Riffler is designed to accurately and reproducibly prepare representative powder sub-samples using the statistically superior method of spin riffling.


Rotary rifflers provide representataive powder samples. Micro Riffler
