Sieving With a 3D Effect and Unique Features
Retsch GmbH & Co KG (Haan, Germany) says in its latest launch pack that the results of a sieve analysis can only be exact and reproducible when using a sieve shaker that fulfils all the necessary technical requirements and claims that its AS 200 and AS 300 - part of the 'control' range - meet the demands for world-wide reproducible sieve analyses, even after short sieving times.
The sieve shakers operate with a patented electromagnetic drive that produces a 3D throwing motion and causes the spring-mass system to oscillate, thus giving the clamped sieves a horizontal to and fro movement. The 3D effect ensures the optimal use of the open sieve area and lets the sample move equally over the whole sieving surface. Further advantages claimed for the system are high stress capacity, extremely smooth operation and short sieving times with high separation efficiency. Sieving time and movement can be set digitally and are carried out reproducibly.
