RO-TAP® tapping test sieve shaker. Innovative particle size analysis with the highest precision requirements

Sieving is an essential process for separating and sorting granular material. Manual sieving by hand is the simplest form, but it can make your day-to-day laboratory work more difficult due to low efficiency and results that are not exactly reproducible. The RO-TAP® tapping test sieve shaker from W.S.TYLER®, our American subsidiary, uses a unique process to provide you with the perfect solution for cube-shaped particles and other solids such as chili powder (from the food industry), abrasive particles and tobacco. The highly efficient test sieve shaker not only reduces your workload, but also delivers reproducible results for quantitative particle size separation and determination. The challenges facing you in your daily laboratory routine are now a thing of the past with the RO-TAP® tapping sieve shaker from W.S.TYLER®.

The functioning mechanism of the RO-TAP® test sieve shaker: tapping motion meets mechanical rotation

The RO-TAP® is considered unique – Unlike conventional test sieve shakers, with an electromagnetic drive, the RO-TAP® operates in two dimensions. It rotates in a horizontal circular motion combined with a vertical tapping motions, imitating the circular and tapping movements of the hand sieve. This tapping sieve method is therefore particularly suitable for unusually shaped particles. The RO-TAP® laboratory test sieve shaker allows the particles to stratify and pass through critical openings in the sieve. This saves you time, since you will never have to re-sieve manually again. The precise coordination of the two motion components also significantly improves the separation efficiency and analysis time. Dry sieving with this standardized and automatic sieving method also gives you reproducible results.

Easy use, precise results

The RO-TAP® test sieve shakers impress with a straightforward operation. Plug in, add bulk material and set the timer on the digital timer - plug and play. The tapping sieve shaker can immediately work on particle size sieving. There is no need for manual adjustment of the amplitude or complicated menus. This ensures that RO-TAP® test sieve shaker can be used quickly, easily and without any special prior knowledge in the laboratory for precise particle size determination.

Wide range of applications, large variety of materials

The RO-TAP® tapping sieve shakers is characterized by its exceptional versatility. It is suitable for a wide range of materials and is used in numerous industries that rely on dry sieving for analytical purposes. In the food industry, it is used to analyze spices, flour products and additives. The abrasives industry uses the tapping sieve shakers to analyze abrasive particles of various grain sizes. In the tobacco industry, it is used for the precise determination of cutting grades and particle distributions. The RO-TAP® by W.S. TYLER® also plays an important role in the quality control of active ingredients and excipients in the pharmaceutical industry. The tapping sieve shaker is even used in mining and mineral processing to separate and analyze the particle size of ores and mineral raw materials.

Low noise for your safety. RO-TAP® RX-29 CE

NEXOPART also has your occupational safety in mind. The W.S. TYLER® RO-TAP® RX-29 CE is equipped with a sound absorbing cupboard designed to suppress noise to ensure that your daily laboratory routine is not only simple but also safe. With its external control system, this machine meets all the occupational safety requirements for application of the CE mark in Europe. Do you work in the abrasives industry? Then the FEPA standard recommends all RO-TAP® models.

FAQ about tapping test sieve shaker and RO-TAP®

What is the RO-TAP® tapping test sieve shaker?

L

The RO-TAP® tapping test sieve shaker is a particle size analyzer that uses a unique combination of tapping motion and mechanical rotation to deliver accurate and reproducible results.

What are the advantages of RO-TAP® tapping test sieve shakers compared to manual sieving?

L

The RO-TAP® tapping sieve shaker reduces the workload, delivers reproducible results and improves the selectivity and analysis time compared to manual sieving.

What is the difference between RO-TAP® tapping sieve shakers and conventional test sieve shakers?

L

In contrast to conventional test sieve shakers, which are operated by electromagnetic drive, the RO-TAP® tapping sieve shakers work two-dimensionally with a horizontal circular movement and vertical tapping pulses, thus enabling more precise particle separation, especially with unusually shaped particles.

Why is the RO-TAP® particularly suitable for analyzing unusually shaped particles?

L

The combination of tapping motion and mechanical rotation means that even unusually shaped particles can be efficiently separated and analyzed, which is more difficult with conventional sieving methods.

What is the difference between RO-TAP® tapping sieve shakers with and without CE certification?

L

The RO-TAP® tapping sieve shaker with CE certification, such as the RO-TAP® RX-29 CE model, is equipped with a sound absorbing cupboard and meets all European safety standards required for CE certification. The machine offer additional safety features, such as an external control system that reduces noise levels and thus increases work safety. In contrast, machines without CE certification have neither a soundproof cupboard nor an external control system.

Are there any other differences between the various W.S. TYLER® RO-TAP® tapping sieve shakers?

L

While most RO-TAP® models are compatible with sieve diameters of 200/203 mm or 300/305 mm and are suitable for up to 3 kg of material in one sieve tower, the RO-TAP® RX-94 allows you to sieve up to 6 kg in two sieve towers.
There are further differences in the compatible mains voltage. Some RO-TAP® tapping sieve shakers can be purchased with a voltage of 110 V at 50 Hz or 230 V at 50-60 Hz. You can check the technical data of each RO-TAP® model in the product details of the respective model:
