3-D Sieving for Heavy Loads

New RETSCH Sieve Shaker AS 450 control for sieve loads up to 20 kg

With the analytical sieve shaker AS 450 control RETSCH have designed their first siever for 400 mm and 450 mm  sieves which operates with a three-dimensional sieving motion. It can be used for dry and wet sieving. The  optimized electromagnetic drive allows for an amplitude up to 2.2 mm which renders the separation process much more effective than with other sieve shakers of this type. Reproducibility plays an important role: The amplitude - which is independent of the sieve load - is continually adjusted. The three-dimensional sieving motion lets the  sample material move equally over the complete sieving surface. This results in high load capacity, extremely  smooth operation and short sieving times with high separation efficiency. When it comes to operating comfort, the AS 450 control meets all the requirements of a modern laboratory. All parameters such as amplitude, time and interval  are digitally set, displayed and controlled. It is possible to store up to 9 parameter combinations for routine tasks.
