The analytical sieve shakers of the series AS 200 are used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. The controllable electromagnetic drive offers an optimal adaption for every product. Sharp fractions are obtained even after short sieving times.
The AS 200 digit cA sieve shaker is recommended whenever controlled amplitude, digital display of vibration height and time and interval operation are required.
Product Advantages
- NEW: controlled amplitude
- suitable for dry and wet sieving
- excellent separation efficiency even with short sieving times
- efficient electromagnetic drive
- 3-D throwing motion which ensures optimum use of the open sieve area and lets the sample move equally over the whole sieving surface
- maintenance-free
- sieve stack up to 510 mm height
- free adjustment of all process parameters (time, amplitude)
- interval operation (fix 10 s)
- digital display of vibration height and time
- easy operation, ergonomic design
Wet sieving with Vibratory Sieve Shakers
There are many applications for which wet sieving is the best solution, e.g. when the material to be tested is a suspension or when a very fine sample (< 45 μm) that tends to agglomerate needs to be sieved. All vibratory sieve shakers from RETSCH can be used for wet sieving. There are special accessories like clamping lids with spray nozzle and collecting pans with outlet available. By placing RETSCH’s venting rings between the sieves, air cushions can expand without letting liquid or sample material escape.
Vibratory Sieve Shaker AS 200 digit cA Accessories & Options
RETSCH sieve shakers can be equipped with a variety of accessories to meet a wide range of application requirements.
- Clamping units
With the RETSCH clamping devices the sieves are clamped safely, quickly and conveniently on the sieve shaker. The clamping devices “comfort” are particularly user-friendly and timesaving.
- Sieving Aids
Chain rings, brushes, cubes, balls (e.g. for reducing agglomerations when sieving particles < 100 μm and keeping the mesh free).
- Accessories for test sieves
Collecting pans, intermediate pans, intermediate rings and sieve lids.
- Sample DividersMeaningful results can only be obtained if the sample represents the original material. Sample dividers produce representative part samples, thus ensuring reproducibility of the analysis.
- Accessories for wet sieving
Clamping lid with nozzle, collecting pans with outlet, venting rings.
- Ultrasonic baths and dryers
Suitable for thorough cleaning of test sieves and for quick, gentle drying of samples and sieves.
EasySieve / EasySieve CFR Evaluation Software
EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects. The software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data. It is simple and convenient to use and is also available in an FDA 21 CFR Part 11-conform version.

Vibratory Sieve Shaker AS 200 digit cA Functional Principle
Each vibratory sieve shaker of the series AS 200 is equipped with an electromagnetic drive that is patented by RETSCH (EP 0642844). This drive produces a 3D throwing motion that moves the product to be sieved equally over the whole sieving surface.
The advantage: high stress capacity, extremely smooth operation and short sieving times with high separation efficiency.
