Sieving for perfect quality control
Model AS 200 basic / digit / control

Innovative technology that sets standards worldwide!
RETSCH analytical sieve shakers are used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. The three-stage series AS 200 enables each user to select the suitable instrument according to his individual requirements and budget. The AS 300 is designed for larger feed quantities. All “control” models are suitable as measuring instrument according to DIN EN ISO 9000 ff.

AS 200 basic
	The economical alternative of the series with familiar RETSCH quality and reliability. With analogue 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 analogue 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. One particular characteristic makes this RETSCH product stand out from others: Instead of the vibration height, also the sieve acceleration independent of the power frequency can be set. Thus, the AS 200 control ensures comparable and reproducible sieving results worldwide. It can be calibrated to ensure 100% reproducibility of sieving results, not only in one device, but among all AS 200 control units! Thus, the requirement for the test materials monitoring according to DIN EN ISO 9000 ff is met. Its microprocessor-controlled measuring and control unit ensures a constant vibration height. With regard to operational convenience, the AS 200 control meets and exceeds all standards of a modern laboratory. All sieving parameters – vibration height, time, interval – are set, displayed and monitored digitally. With the integrated interface and the supplied interface cable, the instrument can be connected to a PC and controlled with the evaluation software EasySieve®. This programme enables you to control the whole sieving process and the subsequent documentation: with convenience and accuracy. The AS 200 control is indispensable for all users who attach importance to precision and operational convenience and work according to the guidelines of the GLP. All RETSCH sieve shakers can be combined with various sieve clamping units. For frequent sieving processes, we recommend the user-friendly quick clamping unit “comfort”.

Technology of AS 200
	All sieve shakers of the series AS 200 and AS 300 work with an electromagnetic drive that is patented by RETSCH (EP 0642844). This drive produces a 3D throwing motion that moves the product to be sieved equally over the whole sieving surface. The advantage: high stress capacity, extremely smooth operation and short sieving times with high separation efficiency.
