WS Tyler RX-230 Spinning Riffler | Sampling and Dividing
The WS Tyler RX-230 Spinning Riffler is a high-quality product that is designed to provide accurate and reliable sampling of dry, free-flowing particles. With its vibratory feeder and sixteen-port dividing head, this Spinning Riffler ensures a constant flow of material from the stainless steel hopper, allowing for easy and efficient sampling.
Representative Sampling
Probably not, unless you split the original sample on a Rotary (spinning) Riffler. Particle Segregation. It is often found that divided solids (powders, granules, etc) segregate by size when they are agitated or shaken. Small particles tend to collect towards the bottom of the container, larger ones on top (the so-called " Brazil Nut Effect".
rotary powder sample splitters RIFFLERS
The sieving rifflerTM Quantachrome is designed to handle larger quantities of powder than the Rotary Micro Riffler. Additionally, particles larger than a particular size and / or foreign bodies can be excluded from the riffling process by attaching a sieve to the top of the hopper. The Sieving Riffler has three basic components: a cylindrical

Sampling a heterogeneous powder using a spinning riffler
Received samples were separated into representative sample portions for powder testing using a spinning riffler (Retsch PT-100). Spinning rifflers are preferred over other techniques (Venables and Wells, 2002) to take representative portions of free flowing powders and work by slowly presenting a sample stream to a rotating set …

Representative sampling of particles with a spinning riffler.
Abstract. Based on a generalised Poisson process, an equation is derived to relate the variance of particle concentration in samples obtained with a spinning riffler to the bulk mixture properties and the riffler operating variables. For the special case of mixtures of uniformly sized spheres of two different densities, this variance is found ...

Retsch : Assisting : Sample Divider : PT 100
A faultless and comparable analysis is closely linked to accurate sample handling. Only a sample representative of the initial material can provide meaningful analysis results.Rotating dividers ensure the representativeness of a sample and thus the reproducibility of the analysis. The sample divider PT 100 divides the sample so exactly that the composition …
