The microprocessor-controlled measuring and control unit of this model ensures a constant vibration height, allowing for 100% reproducibility of results even among different AS 200 control shakers. One particular characteristic makes this RETSCH product stand out from others: Instead of the vibration height, it is possible to set the sieve acceleration which is independent of the power frequency. Together with the possibility of calibration, this ensures comparable and reproducible sieving results worldwide. Thus, all requirements for the test materials monitoring according to DIN EN ISO 9001 are met.
All sieving parameters – vibration height, time, and interval – are set, displayed and monitored digitally which makes operation of the AS 200 control very convenient and quick. Up to 99 standard operating procedures (SOPs) may 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 carry out the whole sieving process and its subsequent documentation with convenience, accuracy and conforming to standards.

Vibratory Sieve Shaker AS 200 control 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 control 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.
- IQ/OQ Documents
We provide IQ/OQ documentation for the „control“ sieve shakers to support IQ/OQ certification by our customers.
- 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.
- Sieving Aids
Chain rings, brushes, cubes, balls (e.g. for reducing agglomerations when sieving particles < 100 μm and keeping the mesh free).
- Ultrasonic baths and dryers
Suitable for thorough cleaning of test sieves and for quick, gentle drying of samples and sieves.

Vibratory Sieve Shaker AS 200 control Application Examples
Efficient Powder Processing in Dental Laboratories with the AS 200 control
Modern dental laboratories like the Dental Laboratories Rehra in Germany use the vibratory sieve shaker AS 200 control for precise classification of metal powders from 3D printing to ensure consistently high material quality. Reliable sieving ensures that only optimally sized particles are returned to the production process, increasing process stability. Agglomerated and oversized particles are removed in advance. At the same time, efficient powder processing helps to significantly reduce material losses and lower costs.
The reproducible results of the AS 200 control support consistently high quality of dental components such as crowns and implants. Fine blasting media used for surface treatment can also be precisely classified and freed from dust and contaminants. This enables the targeted recovery and reuse of valuable blasting media, improving process consistency and reducing operating costs. A uniform particle size distribution ensures consistent and reliable blasting results.
Efficient Separation of Stones from up to 9 Soil Samples with the AS 200 control
In soil analysis, sieving with the AS 200 control prevents distortion of analytical results, reliably separates rocks from soil samples, and simultaneously minimizes equipment damage. Users achieve time-saving and precise analytical results, while maximizing the service life of their devices.
Unbeatable Together: The AS 200 control in combination with the BB 50 jaw crusher is the proven solution for processing large agglomerates from soil samples and can handle up to nine samples in one batch.
Before
After
A 120 g soil sample with agglomerates up to 15 mm in diameter was processed using a 200 x 25 mm sieve with 2 mm round holes.
Soil Analytics – A (not so) Rocky Road to Meaningful Results
Application at Cologne Cathedral – Optimal Protection for Historical Stone Surfaces
The Cologne Cathedral workshop has relied on the AS 200 control for many years to precisely determine particle size distribution in mortar. Various particle fractions can be accurately separated and combined. The goal is to develop mortar with optimal structure and color that almost perfectly replicates the original stone. The use of the AS 200 control eliminates manual sorting, making mortar production more reproducible and efficient.
The result: mortar with the physical properties to fill cracks and simultaneously prevent water penetration.
Before
After
Small particles help to preserve the Cologne Cathedral
Highest Food Quality with the AS 200 control
At Lebensgarten GmbH, the quality of organic cereal flakes is ensured through precise incoming goods inspections. Sieving analysis separates the flakes into different particle size fractions. Special importance is given to the dust fraction of the product with a particle size < 500 μm. This can impair the sealing of packaging on the one hand and negatively affect the consistency of crunchy products on the other.
The patented electromagnetic drive and the three-dimensional throwing motion of the AS 200 control ensure even distribution and optimal separation. Thanks to flexibly adjustable parameters such as amplitude and hole size, various types of flakes can be precisely sieved – ideal for checking raw material quality regarding dust and fine fractions and ensuring high quality in end products.
Measuring Dust - Incoming Inspection with Sieve Analysis
Vibratory Sieve Shaker AS 200 control Functional Principle
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.
