Sieve analysis is a standard process in the analytical, the food and the environmental laboratory and works perfectly if the sieves are cleaned to the last grain.
Elma has a special unit on offer, both for the intensive cleaning of individual sieves and for the simultaneous processing of up to 4 sieves. Special ultrasonic modes provide perfect cleaning results independent of the filling level.
For sieve cleaning, the sieve is placed in the sieve holder and then put into the unit. The special “sieve cleaning” programme uses two ultrasonic modes alternatingly which creates strong active cleaning pulses regardless of the filling level.
The process can be standardized and repeated as required which makes it ideal for defined laboratory applications.
For the use in a laboratory it may be required to apply a cleaning medium which can be rinsed off without residues. For this purpose Elma Clean N1 is reliable and well proven (no dangerous good).
In sieve analysis several sieves are used simultaneously. With the rotating module the throughput can be increased.
The sieves are placed into a universal support rack. The baskets rotate during cleaning and the inclination of the sieves ensures that the removed grains fall out of the sieves automatically.
Gentle ultrasonic cleaning (as opposed to rough manual cleaning), tension of the tissue and mesh size are not changed; the measuring accuracy remains 100% unaltered.
