How to Choose the Right Sieve Shaker for Your Laboratory

February 27, 2026 Blog

Particle size analysis is a key task in many research and industrial laboratories. A sieve shaker delivers reproducible results and saves valuable time. But which device suits your requirements? The selection ranges from compact benchtop units to fully automated systems with comprehensive documentation.

From materials research to quality control and product development – the right sieve shaker machine is crucial for precise analyses. This guide shows you what matters. It explains the different technologies, technical parameters, and practical selection criteria. This way, you find the optimal device for your laboratory.

Why Choosing the Right Sieve Shaker is Crucial

A poorly chosen sieve shaker costs you more than money. Inaccurate results, longer analysis times, and frustrated staff are the consequences. The right sieve shaker machine, however, optimizes your workflows and guarantees precise data. Quality begins with the right selection.

Overview of Different Sieve Shaker Types

Modern particle size analysis requires reliable and standard-compliant sieving methods. Depending on the material properties and required level of precision, different sieve shaker technologies are used in laboratory and quality control environments.

Analytical Sieve Shakers

Analytical sieve shakers operate with an electromagnetic drive that generates controlled three-dimensional sieve motion. The vibration amplitude can be adjusted continuously, allowing precise adaptation to different materials. These systems are ideal for fine powders as well as coarse materials and are suitable for both dry and wet sieving. Short sieving times and gentle sample handling without mechanical impact ensure reliable and reproducible results. RETSCH analytical sieve shakers are widely used in laboratory quality control and research applications.

Models Available:

Throw-Action Sieve Shakers

Throw-action sieve shakers combine vertical and horizontal movements to create a three-dimensional throwing motion. This motion simulates manual sieving and ensures uniform distribution of the sample across the entire sieve surface. The method complies with DIN 66165 and ISO 3310 standards and is particularly suitable for coarse-grained materials such as granulates, sands, and aggregates. RETSCH throw-action sieve shakers deliver reproducible and standard-compliant results.

Models Available:

Air Jet Sieve Machines

Air jet sieve machines use a rotating air jet to disperse the sample and press particles evenly against the sieve mesh. This technology effectively prevents mesh clogging and enables highly precise separation in the fine particle range. RETSCH air jet sieve machines are commonly used for cement, pigments, powders, and pharmaceutical active ingredients, offering significantly higher separation accuracy than mechanical sieving methods.

Models Available:

Selecting the right sieve shaker type ensures accurate, reproducible, and efficient particle size analysis. RETSCH sieve shakers available through Haeberle LABORTECHNIK cover a wide range of applications, from routine laboratory work to demanding fine particle separation.

Important Technical Parameters

Sieve Diameter

Standard sizes are 200 mm and 203 mm (8 inches). For larger sample quantities, 305 mm or 450 mm are available. The diameter directly influences the representative sample quantity.

Number of Sieve Levels

Compact benchtop devices accommodate several sieves. Professional Retsch sieve shakers work with numerous levels simultaneously. More levels mean more detailed particle size distribution in one operation. Keep in mind: each additional level increases the weight of the sieve tower.

Amplitude and Frequency

The amplitude determines the intensity of sieving. The frequency varies depending on device and application. Light powders require higher frequencies with low amplitude. Heavy granulates demand larger amplitudes. Modern devices allow both parameters to be set separately.

Time Control

Digital timers work with second precision. Programmable sequences enable interval sieving with alternating work and pause phases. This method significantly improves results for difficult samples.

Retsch Sieve Shakers: Technology Leader in Comparison

Retsch is considered the technology leader in sieving machines. The AS series offers throw-action sieve shakers for standard-compliant analyses. The Retsch sieve shaker AS 200 works with continuously adjustable amplitude and interval switching. Sieving times are individually adjustable.

The air jet sieve machine e200 LS achieves finest separation cuts. The rotating air jet reliably prevents sieve opening clogging. High repeatability is standard.

Ultrasonic sieve machines like the AS 300 control combine mechanical sieving with ultrasound. Sieve throughputs increase significantly compared to conventional sieving.

Standards and Quality Standards

DIN and ISO Standards

DIN 66165 defines sieve analysis methods. ISO 3310 specifies requirements for test sieves. DIN ISO 2591 describes the execution of sieving. Standard-compliant sieve shakers reproduce the required movement forms exactly.

Calibration

Factory calibration certificates document amplitude and frequency. DAkkS calibrations are required in regulated areas. Calibration intervals depend on frequency of use and regulatory requirements.

Practical Selection Criteria

Sample Volume

Smallest sample quantities: Smaller sieves with fewer levels Standard routine: Medium sieve sizes with sufficient levels Large batches: Large sieves with correspondingly powerful drive.

Materials

Sieve Mesh:

Stainless steel (1.4301/1.4401): universally applicable
Brass: electrically conductive
Plastic (PA, PP): for corrosive media

Housing and Frame:

Stainless steel: pharmaceutical research, food analytics
Aluminum: lightweight construction
Plastic: chemical resistance

Space Requirements

Compact benchtop devices require little floor space Standard devices have moderate dimensions Large devices require correspondingly more space.

Consider accessibility for maintenance and sieve changes.

Noise Level

Good devices operate quietly. Vibration isolation protects the environment. Check your laboratory's noise protection requirements.

Frequently Asked Questions

1. Which sieve shaker is suitable for my sample material?

The right device depends on particle size, density, and flow properties. Fine powders are typically analyzed using analytical or air jet sieve shakers, while coarse materials such as sand or granulates are best handled by throw-action sieve shakers.

2. What is the difference between throw-action and analytical sieve shakers?

Throw-action sieve shakers provide a standardized three-dimensional motion for coarse materials. Analytical sieve shakers offer continuously adjustable amplitudes and are suitable for fine or sensitive samples.

3. Are RETSCH sieve shakers compliant with standards?

Yes. RETSCH sieve shakers comply with relevant standards such as DIN 66165, DIN ISO 2591, and ISO 3310, making them suitable for quality-critical laboratory applications.

4. When is an air jet sieve machine the best choice?

Air jet sieve machines are ideal for very fine, dry powders that tend to agglomerate or clog sieves, such as cement, pigments, and pharmaceutical substances.

5. How many sieve levels are required?

More sieve levels provide a more detailed particle size distribution in a single run but increase the overall weight and drive requirements.
