Superiority in detail-technology from RETSCH
RETSCH products are used in the quality control of solids for a reason. From representative sample
division to precise particle size analysis to professional maintenance of the test sieves - RETSCH
offers you a complete equipment range for perfect results:
§         Sample dividers
Division/extraction of representative partial samples from the bulk
§         Analytical sieve shakers
High-tech devices in various sizes and types of sieving motion (throwing movement with angular
momentum or horizontal circular motion), suitable for wet and dry sieving, can be calibrated
§         Test sieves
Comply with all relevant standards, can be calibrated, manufactured fully automatically which is
unique in the world
§         EasySieve® software
To control the sieve shaker, record weighing data and evaluate and document sieve analyses
according to relevant rules and standards
§         Ultrasonic cleaners and dryers
For the cleaning of test sieves and for the rapid, gentle drying of samples and test sieves.
The AS 200 was awarded a prize for its modern, ergonomic design which at the same time expresses
a high level of technical innovation. The three-stage series AS 200 provides a suitable instrument for
every requirement and budget.
AS 200 basic
The economical alternative of the series with familiar RETSCH quality and reliability. With analog
adjustment of vibration height and sieving time.
AS 200 digit
The standard model of the AS 200 series is recommended whenever digital time display, interval
operation and analog adjustment  along with optical monitoring of the vibration height are required.
AS 200 control
The AS 200 control complies with the highest requirements in quality assurance. Instead of the
vibration height, the sieve acceleration, which is independent of the power frequency, can be set.
Thus, the AS 200 control ensures comparable and reproducible sieving results world- wide.
