Retsch analytical sieve shaker 

0-60 min timer - set/display analog

The electromagnetic drives in these analytical sieve shakers have high load endurance, are quiet running, give the sieve 3-dimensional motion, moving the sieving material evenly over the entire sieve surface for short sieving times with precise separation of fractions. For 100, 150, 200 and 203mm diameter sieves. Will collect up to 9 fractions using 50mm high sieves or 17 fractions using 25mm high sieves. Suitable for wet of dry sieving. Supplied as shaker only.
