W.S. Tyler RO-TAP® RX-812

Designed for coarse testing applications, the affordable RX-812 Coarse Sieve Shaker has the unique capability of using both 8″ diameter and 12″ diameter test sieves simply by using the quick-change adapters provided. Using a singular oscillating motion, the RX-812 has a quiet operation that produces consistent, accurate results.

Designed for dry, free-flowing material, the RO-TAP RX-812 is not recommended for analysis with particles 150 micron (100 mesh test sieves) and coarser.

RO-TAP Sieve Shaker Maintenance Kit

To ensure lasting dependable service Sieve Shakers must occasionally be upgraded with parts that are long-wearing, durable and cost effective. Maintenance kits are available for the replacement of parts due to normal wear and tear.

RO-TAP Sound Enclosure

This cabinet/test stand is designed to reduce the operating noise levels of RX-29, RX-30, and RX-812 RO-TAP sieve shakers. Fabricated from 18 gauge steel with a 1” metal face, these sound enclosures are outfitted with acoustic foam, reducing noise levels from 85 to 78 dB.

RO-TAP Test Stand

The W.S. Tyler RO-TAP Test Stand is designed to provide a secure testing platform for your RO-TAP device. Outfitted with pre-drilled holes, this test stand allows RO-TAP sieve shakers to be bolted down, preventing the device from shifting during operation.

Sampling Splitter

W.S. Tyler sample splitters are designed with precision in mind. This instrument facilitates accurate and repeatable results by accurately and efficiently splitting bulk samples.

Sieve Conversion Kit

The RO-TAP Sieve Conversion Kit enables RO-TAP users to utilize different test sieve diameters with a single sieve shaker. The kit consists of two inserts, one on top of the test sieve stack and one at the bottom.

These inserts essentially wedge test sieves with a diameter too small for the sieve shaker housing, allowing the sieve stack to function correctly.

Wet Test Sieving Kit

The W.S. Tyler Wet Sieve Kit is an assortment of hardware designed to enable wet sieving capabilities using standard RO-TAP devices. This specialized kit includes everything you need to test material suspended in water accurately.

The included water reservoir allows complete control over the water flow, ensuring accurate and repeatable wet-sieving results. Most importantly, this kit’s components are constructed using high-quality materials, which allow them to withstand heavy exposure to liquid without deteriorating.

Essential Product Information For You

Undeniable Precision

The strong oscillating motion of the RO-TAP RX-812 ensures efficient particle movement. Despite not having brute hammer taps, the RX-812 is more than capable of producing accurate results.


Seamless Maintenance

With the RO-TAP, little to no maintenance is the bar. All moving wear parts can be easily accessed in-house, allowing you to get your device up and running with minimal downtime.


Test Sieve Versatility

Both 8” and 12” test sieves can be accommodated by the RO-TAP RX-812. With specialized reduction kits you can use both sieve diameters with a single device.
