VIBRATORY SIEVE SHAKERS Vibratory Sieve Shaker AS 300 control The worldwide unique RETSCH technology: sieving with controlled acceleration! The Sieve Shakers AS 200 control and AS 300 control are activated in their natural fre­ uency. This q means, the sieving fre­ uency q changes with the load of the instrument. It depends on the weight of the sieve stack and the quantity of the loaded product to be sieved. In order to ensure the reproduci­ i­ity bl of the results even in short-time sieving pro­ edures, the default setc ting of the vibration height can be switched to sieve acceleration (sieving...
