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 very short sieving times.
With its all-digital controls, up to 99 sieving programs and calibration certificate the sieve shaker AS 200 control is indispensable for all users who attach importance to precision and operational convenience and need to comply with the guidelines of the ISO 9001.
The AS 200 control can be calibrated to ensure 100% reproducibility of sieving results, not only in one device, but among all AS 200 control units! Accordingly, this model is perfectly suited to check particle size distributions for quality control, for example between suppliers and customers.

Operation of the AS 200 control is convenient and easy. All sieving parameters – vibration height, time, interval – are set, displayed and monitored digitally. Up to 99 parameter combinations (SOPs) can be stored for routine analyses. Through the integrated interface the instrument can be connected to a PC and controlled with the evaluation software EasySieve®. This program enables the user to control the whole sieving process and the subsequent documentation with convenience and accuracy.
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.
The sieve shakers of the control series can be equipped with a variety of accessories to provide for a wealth of application requirements.
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.
Collecting pans, intermediate pans, intermediate rings and sieve lids.
Clamping lid with nozzle, collecting pans with outlet, venting rings.
Chain rings, brushes, cubes, balls (e.g. for reducing agglomerations when sieving particles < 100 μm and keeping the mesh free).
We provide IQ/OQ documentation for the „control“ sieve shakers to support IQ/OQ certification by our customers.
Suitable for thorough cleaning of test sieves and for quick, gentle drying of samples and sieves.
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 compliant version.
Vibratory sieve shakers are frequently used for grain size analysis of cement clinker, chemicals, coffee, construction materials, fertilizers, fillers, flours, grains, metals powders, minerals, nuts, plastics, sand, seeds, soils, washing powder, etc.

All sieve shakers of the series AS 200 work 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.
