Analysis and testing of powders for chemical assay and physical measurements, such as particle size, density and surface area,
often requires reduction of a large sample quantity into smaller amounts. Therefore, it is necessary that the sub-sample
ultimately analyzed shall be representative of the initial lot or batch for reproducible and valid data.
The Sieving Riffler and Rotary Micro Riffler are designed to accurately and
reproducibly prepare representative powder sub-samples using the statistically superior method of spin riffling. |
