Ultrasonic Sieve Shakers for Laboratories
The ultrasonic sieve shaker for laboratory sieves from Hielscher sieves, fractionates, classifies or separates powders quickly and reliably. The ultrasonic ring is simply clamped between standard lab sieves or test sieves. The ultrasonic vibrations are transmitted to all sieves in the sieve stack.
Ultrasonic Sieve Shaker for Efficient Powder Screening
Mineral or metallic powders, pigments or powder coatings, crystalline materials, spices, soil samples, cement powders or ceramic mixtures… – The Hielscher ultrasonic sieving system is suitable for almost all materials. In fact, many wet powders and slurries can be ultrasonically screened, too.
Using the ultrasonic sieve shaker is very easy: When stacking the test sieves, the ultrasonic ring is positioned between two sieves and tighten as usual. You can also use the ultrasonic sieve shaker together with conventional sieve shakers.

Improve Particle-Size Analysis, Fractionation and Quality Control with the Ultrasonic Sieve Shaker
Ultrasonic sieving has considerable advantages over traditional sieve shakers. The high-frequency vibrations, which agitate of the sieve mesh do not cause overstretching of the mesh. As a result, the mesh does not lose its tension prematurely. With ultrasonic sieves also larger powder quantities can be sieved easily at once.
Furthermore, using ultrasonic vibrations prevents that the material to be screened is shifted horizontally over the screen mesh. This prevents the material from being abraded. Especially with abrasive powders, conventional sieve shakers also cause a strong abrasive wear of the sieve mesh itself. With the Hielscher ultrasonic sieve shaker you can use your sieves much longer!
The ultrasonic vibrations activate the entire sieve surface – right to the edge. This leads to more accurate sieving results.
Hielscher Ultrasonic Sieve Shaker – Easy and Flexible to Use
The Hielscher ultrasonic sieve shaker is available for all standard laboratory sieves and test sieves with 200mm or 8 inch diameter. In addition, Hielscher also manufactures sieve shakers for other diameters and for customer specific requirements.
Of course, the Hielscher ultrasonic sieve shaker can be operated continuously, e.g. to sieve powder coatings, metal powders or other materials continuously in production or to separate lumps and agglomerates from powders.

Frequently Asked Questions about Ultrasonic Sieve Shakers for Laboratories
What is an ultrasonic sieve shaker?
An ultrasonic sieve shaker is a laboratory device that uses high-frequency ultrasonic vibrations to agitate sieve mesh for efficient powder screening and classification. The ultrasonic ring is clamped between standard laboratory sieves, transmitting ultrasonic vibrations throughout the entire sieve stack for fast and reliable results.
How does an ultrasonic sieve shaker work?
The ultrasonic ring is positioned between two sieves when stacking test sieves and tightened as usual. Ultrasonic vibrations are then transmitted to all sieves in the stack, agitating the mesh at high frequency to prevent clogging and ensure accurate powder fractionation.
What are the advantages of ultrasonic sieving over conventional sieve shakers?
Ultrasonic sieving offers several key advantages:
- Extended sieve life: High-frequency vibrations do not cause overstretching of the mesh, preventing premature loss of tension.
- Reduced abrasion: Ultrasonic vibrations prevent material from shifting horizontally over the screen mesh, reducing wear – especially important for abrasive powders.
- Larger batch capacity: Larger powder quantities can be sieved easily at once.
- More accurate results: Ultrasonic vibrations activate the entire sieve surface, right to the edge, leading to more precise sieving outcomes.
What types of materials can be screened with an ultrasonic sieve shaker?
The ultrasonic sieve shaker is suitable for almost all materials, including:
- Mineral and metallic powders
- Pigments and powder coatings
- Crystalline materials
- Spices, flours, food powders
- Soil samples
- Cement powders and ceramic mixtures
- Wet powders and slurries
- Precious and advanced materials
Which laboratory sieves are compatible with the ultrasonic sieve shaker?
The Hielscher ultrasonic sieve shaker is available for all standard laboratory sieves and test sieves with a 200mm (8 inch) diameter. Custom diameters and customer-specific requirements can also be accommodated.
Can the ultrasonic sieve shaker be used with conventional sieve shakers?
Yes. The ultrasonic sieve shaker can be operated in conjunction with conventional sieve shakers, providing flexibility for various laboratory workflows.
Can the device be operated continuously?
Yes. The ultrasonic sieve shaker can run continuously, making it ideal for applications such as screening powder coatings, metal powders, or other materials in production environments, as well as separating lumps and agglomerates from powders.
How is the intensity of ultrasonic vibrations controlled?
The intensity of the ultrasonic vibrations can be easily adjusted on the generator, allowing users to control the sieving intensity. A timer and a fully adjustable interval mode are standard features.
Where are Hielscher ultrasonic devices manufactured?
Hielscher Ultrasonics devices are exclusively manufactured in Germany. The company is an owner-managed, ISO-certified business with over 30 years of experience in ultrasonics and known for their reliable, robust and high-quality sonciators.
Can Hielscher perform test sieving on my samples?
Yes. Hielscher offers a laboratory service where they can perform test sieving on customer samples. Interested users can request additional information or discuss their sieving application through the contact form or by phone.
