    The well-proven RETSCH sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the sieve fabric is precisely joined into the frame and tautened. RETSCH test sieve provides a clear and accurate labeling with full traceability.

    The sieves can be easily combined with all other sieve brands. Each sieve that leaves our company comes with a test report or, at your request, with a special inspection certificate in conformity with national and international standards (PDF). RETSCH calibration certificates confirm a great number of precision measurements, thus ensuring an even higher statistical reliability for your quality control.

    RETSCH test sieves are available in many sizes and varieties.

    The well-proven RETSCH sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the sieve fabric is precisely joined into the frame and tautened. The individual laser engraving of each RETSCH test sieve provides a clear and accurate labeling with full traceability.

    The sieves can be easily combined with all other sieve brands. Each sieve that leaves the company comes with a test report or, at your request, with a special inspection certificate in conformity with national and international standards (PDF). RETSCH calibration certificates confirm a great number of precision measurements, thus ensuring an even higher statistical reliability for your quality control.

    RETSCH test sieves are available in many sizes and varieties, primarily in the four frame sizes most widely used in laboratory analytics:

    • 200 x 50 mm, 200 x 25 mm
    • 8“x 2“ (203 x 50 mm), 8“x 1“ (203 x 25 mm)

    Application Examples

    Cement Clinker, Chemicals, Coffee, Construction Materials, Fertilizers, Fillers, Flours, Grains, Metal Powders, Minerals, Nuts, Plastics, Sand, Seeds, Soils, Washing Powder, …

    Product Advantages

    • Stainless steel sieve frame with high form stability
    • High degree of corrosion resistance and easy cleaning thanks to high-alloy stainless steel
    • Sieve mesh sizes from 20 µm to 125 mm
    • Permanently tight sieve fabric
    • Excellent product quality due to extensive optical inspection
    • Maximum stability and optimum sealing when used in sieve stacks thanks to the o-ring which is placed in the recess designed for this purpose
    • Clear and precise labeling of the sieves with full traceability based on individualized laser engraving

    Function Principle

    Prior to delivery, each test sieve is optically measured and granted a test report. On request, an inspection certificate with the measuring results in tabular and graphical form or a calibration certificate with detailed statistics is delivered.

    As a special service, we offer to recalibrate your test sieves. After the standard measuring process, all relevant data is recorded and confirmed in the calibration certificate, if desired.

    Applications: Separation, Fractioning, Particle Size Determination
    Field of Application: Agriculture, Biology, Chemistry / Plastics, Construction Materials, Engineering / Electronics, Environment / Recycling, Food, Geology / Metallurgy, Glass / Ceramics, Medicine / Pharmaceuticals
    Feed Material: Powders, Bulk Materials, Suspensions

    EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects, due to the fact that the software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data. It is more simple and more comfortable to use than ever before, and, to put it simple, “easy”.

    The new EasySieve CFR version offers compliance with FDA 21 CFR Part 11.

    Application Examples

    Cement Clinker, Chemicals, Coffee, Construction Materials, Fertilizers, Fillers, Flours, Grains, Metal Powders, Minerals, Nuts, Plastics, Sand, Seeds, Soils, Washing Powder, …

    Product Advantages

    • Automatic registration, evaluation and administration of measurement data
    • Logical design, self-explanatory
    • Measurement protocol in accordance with standards
    • Cmplex transformation into charts and tables
    • Dta link of different measurement instruments
    • Atomatic detection and configuration of common analytical scales
    • Cmprehensive data export
    • EasySieve CFR: Itegrated AuditTrail for consistent documentation of every working step of the sieving process
    • EasySieve CFR: Al data is stored in encrypted form in data bases
    • EasySieve CFR: AuditTrail Manager provides four different user levels: from administrator to standard user

    Function Principle

    Parameter entry
    All available parameters (such as sieve stack configuration, dead weight of the sieve, sieve shaker settings) as well as the characteristics, which may have to be calculated, can be entered by clicking with the mouse in the corresponding fields.

    Sieve analysis
    The program accepts automatic and manual data entries from both scale and sieve system. All RETSCH sieve shakers of the series “control” can be automatically controlled with EasySieve®. After the sieve analysis is completed, the loaded sieves are reweighed. By determining the weight difference, the program automatically detects the mass proportions and assigns them accordingly to the corresponding fractions.

    Evaluation
    The EasySieve software calculates all common particle distributions as well as the characteristic values of the particle size, thus making it possible to present the results in standard presentation forms, such as tables and charts. Cumulative throughput or residual values, distribution density and histograms can be included in the standard particle size distributions.

    Data export
    All measured data can be printed, saved and exported as tables and charts. Automatic transfer into the LIMS system is possible.
