Laboratory Particle Rifflers and Splitters


W.S. Tyler Spinning Riffler



The RX-230 Spinner Riffler uses a vibratory feeder to provide a constant flow of material from the stainless steel hopper.  The vibrating feeder then feeds the sampling tubes from 1 to 16 individual samples.  Each sample can then be capped ans stored immediately, with minimal handling and little chance for outside contamination.

Spin riffling is the method of choice for sampling accuracy and reliability for dry, free flowing particles. This unit wil virtually eliminate operator error and bias associated with othe types of sampling devices.

The RX-230 Spinning Riffler includes a sixteen-port dividing head, a set of sixteen standard tube sample vessles, a sample drum to contain the vessels and a hopper plate for positioning the vessles in the drum.  All of these parts are available as replacement parts.

Dimensions:  13" wide x 20 1/2" deep x 23" high
