Superiority in detail – technology from RETSCH

Ease of use and efficiency

Clamping test sieves does not get any easier, faster and safer than with theclamping device “comfort”. The trick: simply press the upper lever to clampthe sieves tight. After the sieving is completed, the sieve stack can be with-drawn without having to completely take off the lid. Thus, time and powerare saved.

In all “control” models, 9 different parameter combi-nations can be saved. Thus, repetitive sieve analyses canbe performed quickly and efficiently. Errors due to wrongparameter entries are prevented.

High quality test sieves

Due to a unique and highly modern production process,RETSCH offers you test sieves of unparalleled quality andprecision. Thus, RETSCH meets and exceeds the highestrequirements of reliable particle size analyses. Bettersieves guarantee better, exact results.

Form follows function

RETSCH laboratory instruments also show their technical superiority fromthe outside. The AS 200 was awarded a prize for its modern, ergonomicdesign which at the same time expresses a high level of technical innovation.

Why particle size analysis?

The knowledge of particlesize and distribution indisperse solids is veryimportant for researchand development, pro-duction and qualityassurance.

The following list showsproduct properties thatdepend on the particlesize distribution:

■ mechanical propertiesof bulk goods

■ surface reaction■ insulating and

absorbing properties■ flavor■ mixability■ wear resistance■ filtration ability

■ stress and breakingbehavior

■ agglomeration due toadhesive forces

■ conductivity■ extinction

Unique operation in accelerated mode

In RETSCH sieve shakers the intensityof the movement can be set either inmm as vibration height or in “g” asacceleration (acceleration due togravity, 9.81 m/s2), independent ofthe power frequency. “Sieving with

equal acceleration” means obtaining worldwide comparable and reproducibleresults, completely independent of operational parameters such as powerfrequency, load, age or condition of the machine. This feature is unique toRETSCH sieve shakers.

Calibration

All RETSCH analytical sieve shakers of the series “control” and all RETSCH test sieves can be calibrated and thus may be used in quality controlaccording to DIN EN ISO 9000 ff. RETSCH supplies high-quality productsthat you can rely on.

be sieved equally over the wholesieving surface. The advantage:high load capacity, extremelysmooth operation and shortsieving times with high separationefficiency.

Innovative technology that sets standards worldwide!

RETSCH analytical sieve shakers are used in research & development, qualitycontrol of raw materials, interim and finished products as well as in productionmonitoring. The three-stage series AS 200 provides a suitable instrument forevery requirement and budget. The AS 300 is designed for larger feed quanti-ties. All “control” models can be used as measuring instrument according toDIN EN ISO 9000 ff.

AS 200 control

The AS 200 control complies with thehighest requirements in quality as-surance. One particular characteristicmakes this RETSCH product stand outfrom others: Instead of the vibrationheight, the sieve acceleration, whichis independent of the power fre-quency, can be set. Thus, the AS 200control ensures comparable and re-producible sieving results world-wide. It can be calibrated to ensure100% reproducibility of sieving results,not only in one device, but among allAS 200 control units! Thus, the re-quirement for the test materialsmonitoring according to DIN ENISO 9000 ff is met. Its micropro-cessor-controlled measuring andcontrol unit ensures a constant vibra-tion height. With regard to operationalconvenience, the AS 200 control meetsand exceeds all standards of a modernlaboratory. All sieving parameters –vibration height, time, interval – areset, displayed and monitored digitally.Up to 9 parameter combinationscan be stored for routine analyses.Through the integrated interfacethe instrument can be connected to aPC and controlled with the evaluationsoftware EasySieve®. This program

enables you to control the wholesieving process and the subsequentdocumentation with convenience and accuracy.

The AS 200 control is indispensablefor all users who attach importanceto precision and operational con-venience and work according to theguidelines of the GLP.

All RETSCH sieve shakers can be com-bined with various sieve clampingunits. For frequent sieving processes,we recommend the user-friendlyquick clamping unit “comfort”.

AS 300 control

The AS 300 control is specificallydesigned for test sieves with a dia-meter of 305 mm (12"). Comparedto sieves with a diameter of 200 mm,a 2.25 times larger sieving surface isthus available. Therefore, the averagesieving times can be greatly reducedwith the AS 300 control. Another advantage is the large feed quan-tity (up to 6 kg) that can be separa-ted in one working run. Repetitiveoperations can be greatly simplifiedwith the possibility to store up to9 parameter combinations directlyin the sieving instrument.For perfectly reproducible sieving re-sults, the AS 300 control can be pro-

with CE standardsThe chart makes it clear: evenwith large differences in the fre-quency, sieving processes withequal acceleration always achievefully matching results, indepen-dent of the sieving time. This isbecause the sieve acceleration isthe decisive factor for the quickpassage of the particles throughthe sieve.

The worldwide uniqueRETSCH technology:sieving with controlledacceleration!

The sieve shakers AS 200 controland AS 300 control are activatedin their natural frequency. Thismeans, the sieving frequencychanges with the loading of theinstrument. It depends on theweight of the sieve stack and thequantity of the loaded product tobe sieved. In order to ensure thereproducibility of the results evenin short-time sieving procedures,the default setting of the vibrationheight can be switched to sieveacceleration (sieving with equalacceleration). Thus, the instru-ments work completely indepen-dent of operational parameterssuch as power frequency,loading, age, or condition ofthe unit.

Therefore, the RETSCH sieveshakers AS 200 control andAS 300 control are the only sieveshakers to feature the possibilityof eliminating influences of errorby different sieving frequenciesvia automatic adjustment of theamplitude (patents D 19 522 987,USA 5,791,494). An amplitude ofmore than 2 mm can be achievedunder all nominal load conditions,and the sieve acceleration achievedin this can be as high as 17 g (1 g = 9.81 m/s2).
