The AS 300 model has all the benefits of the AS 200 control but is designed for test sieves with a diameter up to 315 mm, providing a sieve surface which is approximately 2.5 times larger. Therefore, the AS 300 is able to separate up to 6 kg of material in one working run. Repetitive operations are greatly simplified with the possibility to store up to 99 standard operating procedures (SOP). For perfectly reproducible sieving results, the AS 300 control can be programmed with sieve acceleration independent of the power frequency instead of vibration height.
The microprocessor-controlled measuring device monitors and automatically readjusts the vibration height. All sieving parameters are set, displayed and monitored digitally. The AS 300 control can be calibrated, and is thus suitable for test materials monitoring. Like all instruments of the “control” series, the AS 300 has an integrated interface for using the evaluation software EasySieve® to control, set and visualize all parameters, including complete documentation of the sieving process
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-conform version.
RETSCH's vibratory sieve shakers are ideally suited for separation, fractioning and particle size determination of cement clinker, chemicals, coffee, construction materials, fertilizers, fillers, flours, grains, metals powders, minerals, nuts, plastics, sand, seeds, soils and washing powder.

AS 300 har et elektromagnetisk drivverk som RETSCH har patent på (EP 0642844). Dette drivverket sørger for en tredimensjonal kastebevegelse som får siktematerialet til å bevege seg jevnt over hele sikteflaten. Fordelene med dette er høy kapasitet, ekstremt, rolig kjøring og kort siktetid på grunn av høy sikteeffektivitet.
