Ultrasonication – Feasibility and Process Optimization
In our process lab, we offer devices for the sonication of liquid volumes from 0.1mL to approx, 1000 liters per hour. Equipment for inline refrigeration or heating of the process material is available to control the sonication temperature. The sonication pressure can be increased to approx. 30 bar. Our pumps can handle high viscosity, high solids concentration materials at adjustable flow rates.
For the preparation of your test material, we are equipped with all required equipment such as mixers, stirrers, heaters, microwave etc.
Analysis of Sonicated Samples
Analysis and evaluation of the quality and performance of the ultrasonic process is an important part of your visit in our process lab. The post-sonication analysis shows you how the material responses to ultrasonics and reveals what sonication parameters give you the best results. Below you can find an overview over the most important analytical tools, we offer in our process lab.
Comprehensive Lab Reports of Sonication Trials
Our service includes a full lab report which includes all ultrasonic process parameters and analytical measurements. Pictures, photos, tables, and short videos visualize the work performed during the booked lab service in our ultrasonic technical center. The detailed lab report enables you to reproduce all results.

Particle Size Characterization
Laser Diffraction: The Microtrac S3500 employs the patented Tri-laser technology to provide accurate, reliable particle size information. Even in the sub-micron range, measurements are made without typical sample-to-sample variation evident in many other systems. By increasing the number of light sources, the unique Tri-laser technology makes more effective use of photo-detection devices, while maintaining maximum stability and alignment of the optical system. Microtrac S3500 complies with or exceeds ISO 13320-1 Particle Size Analysis- Laser Diffraction Methods.
The Microtrac S3500 is suitable for particle size characterization from 21,5 nm to 1408 µm
Dynamic Light Scattering: The Nano-flex characterizes colloidal systems by dynamic light scattering within a size range of 0.3 nm to 10 µm and is suitable for material systems with concentrations from ppm up to 40% vol., depending on substance type. Minimum volume for measurements is 1 droplet.
The Nano-flex is suitable for particle size characterization from 0.3 nm to 6.5 µm.
