Sieving : Particle size analysis according to DIN EN ISO 9000 ff
Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control. Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:
RETSCH sieve shakers, test sieves and evaluation software provide the key to easy, rapid, reproducible and, above all, accurate analyses.
Sieve Shakers
RETSCH sieve shakers and sieving machines not only covers a wide measuring range. Thanks to different sieving motions and sieve sizes, the RETSCH sieve shaker range is suitable for almost any bulk material.
Our sieve shakers and sieving machines produce exact and reproducible results and comply with the requirements for the test materials monitoring according to DIN EN ISO 9000 ff.
1 - Vibratory sieve shaker: The analytical sieve shakers such as in 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.
2 - Air jet sieving machine: The new Air Jet Sieve AS 200 jet is particularly suitable for sieve cuts of powdered materials which require efficient dispersion and desagglomeration. The option to store up to 10 SOPs and the automatic vacuum regulator (accessory) guarantees reproducible and meaningful results. Innovative features such as the Open Mesh function, the selection of the nozzle speed as well as optional use of standard 2″ high test sieves perfects the new air jet technology.
3 - Tap sieve shaker: The analytical sieve shaker AS 200 tap is used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. Its tapping motion supports the sieve analysis of certain products such as activated carbon, abrasives, metal powder, spices and diamonds, as specified in the corresponding standards.
4 - Horizontal sieve shaker: The analytical sieve shaker AS 400 control is used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring.
The AS 400 control is used for the sieving of dry goods with test sieves of a diameter up to 400 mm. In this, the uniform, horizontal circular motion ensures exact separation of fine and coarse-grained products.
With its all-digital controls and calibration certificate the AS 400 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.

Test SievesThe well-proven RETSCH test sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the fabric of each test sieve is precisely joined into the frame and tautened. The individual laser engraving of each test sieve provides a clear labeling with full traceability.
EasySieve software
EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects, due to the fact that 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 more simple and more comfortable to use than ever before, and, to put it simple, “easy”.
The new EasySieve CFR version offers compliance with FDA 21 CFR Part 11.
