The analytical sieve shaker AS 300 is used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. The AS 300 is particularly designed for test sieves with a diameter of 305 mm (12"). Compared to sieves with a diameter of 200 mm, a 2.25 times higher sieving surface is thus available. Therefore, the average sieving times can be greatly reduced with the AS 300 control.

The AS 300 works 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.
