Dispersibility & stability analyzer TURBISCAN DNS

Dispersibility corresponds to uniformly dispersing particles into liquids and with a particle size as close as the primary particle size. Being crucial to match product specifications and get the most value out of the used raw material, dispersibility is impacted by the particle-to-particle interaction and must, as stated in ISO/TS22107:2021, be measured while processing the particle into the liquid and native sample (no dilution, no mechanical stress).

Thanks to the online capabilities of the TURBISCAN DNS, it is the first ready-to-use instrument to investigate particle dispersibility and helps the operator to formulate safe and cost-effective higher-performance formulations. Please take a look at our numerous applications and measurement examples to find the right raw materials, optimize processes, and look for alternative solvents.

The TURBISCAN technology offers a significantly faster (up to 1,000 times) and more reliable detection of sedimentation compared to visual observation. Furthermore, naked-eye observation makes it difficult to calculate the migration rate and is prone to error and misinterpretation. In contrast, the TURBISCAN technology provides a fast and non-destructive way to detect and quantify sedimentation and particle size over time and can detect even small changes in highly concentrated samples without any dilution or mechanical stress. This makes it ideal for analyzing complex suspensions and formulations, and getting a quicker, reliable, and more accurate answer on sedimentation monitoring. 

The TURBISCAN has been extensively used to measure the physical stability of formulations and colloidal systems. This technology helps the formulator to save time and precisely rank and quantify the samples’ stability in different trials or batches. It applies to native samples, even on very highly concentrated formulations. Not only saving time, the TURBISCAN also provides destabilization speed and metrics as well as robust analytics to make shelf-life predictions. The TURBISCAN technology follows ISO/TR 13097:2013’s recommendations and is ideal when it comes to quickly and accurately measuring stability. Stop the guesswork and make decisions based on facts!

When it comes to measuring droplet migration and creaming behavior in emulsion systems, the TURBISCAN technology has several advantages for formulators. On one hand, it provides a fast measurement (up to 1,000 times faster than visual observation) of native samples and a non-destructive way to detect and measure droplet migration. On the other hand, the migration rate can easily be determined and helps the formulator to compare formulas, making it ideal for analyzing complex emulsions with a wide range of droplet sizes and concentrations. Additionally, the TURBISCAN technology provides insights into the mechanisms driving droplet migration, which can be used to improve formulation and processing conditions. Overall, the use of TURBISCAN technology in emulsion analysis leads to faster, more accurate, and more reliable results compared to traditional methods.

Dehydrated powders are used in various industries – such as the food, cosmetics and pharmaceutical industries – to maintain the quality and shelf-life of products. However, the reconstitution and rehydration of these powders can pose several challenges, such as ensuring the homogeneity, stability and functionality of the reconstituted product. It is therefore of utmost importance to investigate the factors that influence the reconstitution and rehydration behavior of dehydrated powders and optimize the conditions to achieve the best performance. Thanks to the "online" and "at rest" measurements you can study the ability of the powder to rehydrate, as well as the stability of the reconstituted product, in a single experiment and with a single device. For more information, please read our application note on reconstitution of milk powder.

Plant proteins are increasingly popular in the food industry, as they offer various health, environmental, and ethical benefits compared to animal proteins. However, incorporating plant proteins into food products poses some challenges, as they have different physicochemical and functional properties than animal proteins. One of the main issues is the solubilization of plant proteins: due to their poor solubility, the solubilization affects their emulsification and stability properties. There are no methods to characterize the overall plant protein performances and chemists have to utilize multiple experiments and instruments in order to have a complete understanding of plant protein performances. Thanks to the TURBISCAN DNS solubilization speed and quality, emulsification and stabilization properties can be measured with the very same instrument and in a single experiment.
