Retsch GmbH, Haan, Germany, has announced a new generation of its vibratory sieve shakers. The new sieve shakers are claimed to offer easy and convenient operation, ensuring accurate, reliable and user-friendly grain size analysis. The Retsch AS 200 and AS 300 vibratory sieve shakers also include optimised control and vibration decoupling, resulting in the machines running very quietly.
Improvements to the model range include the updating of the entry-level model AS 200 basic to include digital control, a standard feature on other models in the AS 200 series. Parameters such as performance and time are now visible on the display.
The AS 200 digit cA model now operates with controlled amplitude which is indicated in the display, just like the sieving time. The high-end model AS 200 control has been further optimised and can now be equipped with up to ten sieves. New features include the storage of up to 99 sieving programs as well as USB connection for use of EasySieve® evaluation software. The AS 300 control for sieves with a 300 mm diameter is now also available in the new design.
