Principles of operation
The Riffle Divider (RF) is designed for manual representative dividing of dry, granulated and powdered sample material.
After a representative sample extraction has been effected, further reduction is the major prerequisite for exact analysis results in accordance with the characteristics of the bulk quantity. Due to its special sampling method, the Riffle Dividers provide an accuracy which is superior to all other manual procedures.
The sample material cascades into the two collecting receptacles through a number of slots, which are arranged opposite to each other. With each dividing process, the feed quantity is halved until the required sample quantity has been reached.
