Boost your productivity with easy, reliable particle sizing solutions

Suited to all types of sieving tasks, our Octagon 200 Sieve Shaker is lightweight enough to be portable but has also proven its capability as a robust performer.

Using an innovative electromagnetic drive combined with a 3D sieving motion, the Octagon 200 is fast and efficient. A digital display and quick-release clamping system combine to make operation easy for laboratory personnel, and to further speed up sample processing. The Octagon 200 Sieve Shaker accepts up to 8 full-height or 16 half-height 200mm (8”) diameter sieves and is suitable for dry or wet sieving.

Our manual RO-TAP Sieve Shakers provide reliable, accurate and consistent particle size analysis. We have two models available – the RX-29 is designed for testing with 200 mm (8”) diameter test sieves, either six full-height or 13 half-height, and the RX-30 is designed for testing with 300 mm (12”) diameter test sieves, either four full-height or eight half-height. Both models require sieves to be manually loaded for each test run, and the initial sample and the resulting fractions weighed out by hand.

 Our RO-TAP Sieve Shakers are suited to laboratory setting applications which require a rotary shaking and tapping action. Manufactured from high-quality materials, they are very durable machines and have proven their ability to perform long-term.

The main purpose of particle sizing is to determine the distribution of particle sizes within a material sample. This is critical because the size of particles can affect the physical and chemical properties of materials.

Particle size by sieve analysis is a method where a sample of material is separated into fractions by passing it through a series of sieves with different mesh sizes. Each sieve retains particles larger than its mesh size, while smaller particles pass through to the next sieve. The mass of material retained on each sieve is weighed, and the particle size distribution is determined based on these weights. Sieve analysis is widely used in industries like mining, construction, and pharmaceuticals due to its simplicity and reliability.

A sieve shaker is a machine used to automate the process of sieve analysis. It shakes or vibrates a stack of sieves containing a material sample to ensure particles are evenly distributed and can pass through the appropriate sieve sizes. The shaking motion replicates manual sieving but with greater consistency and efficiency. Sieve shakers are commonly used in laboratories for particle size analysis in industries such as mining, agriculture, and pharmaceuticals.
