Sieving & Fractioning
Only if the size distribution remains constant, a steady product quality can be guaranteed.
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:
- the strength of concrete depends on the particle size of the cement
- the taste of chocolate is influenced by the fineness of the cocoa
- the flow characteristics and solubility of washing powders depend on the fineness and particle shape of the basic materials
Retsch sieve shakers, test sieves and evaluation software provide the key to easy, rapid, reproducible and, above all, accurate analyses.

Vibratory Sieve Shakers
Particle size determination ranging from small volumes to bulk materials. Exact and reproducible results and comply with the requirements for the test materials monitoring according to DIN EN ISO3310-1,-2,-3 and ASTM E11.
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.
Air Jet Sieveing Machine
The Air Jet Sieve AS 200 jet is particularly suitable for sieve cuts of powdered materials which require efficient dispersion and deagglomeration. The option to store up to 10 SOPs and the automatic vacuum regulator (accessory) guarantees reproducible and meaningful results.
Test Sieves
The 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.
- Evaluation Software
- Perfect Addition
The sieve software EasySieve exceeds manual evaluation in many aspects, due to the fact that it automatically controls 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”.
Microtrac MRB, a leader in particle characterisation is the perfect addition to sieve analysis, making particle analysis more accurate, more effective and more convenient.
