Control Tech

Microplastic Quantification

Our control technology is based on a proprietary patented method that guarantees high efficiency, precise identification, and quantification of all types of microplastics in all water matrices, including complex matrices such as wastewater with high levels of organic matter.

Technological Advantages
  • Robust & Standardisable Lab Method.
  • Method Tested & Verified on all kind of complex aqueous matrices.
  • High Accuracy & Efficiency for all types and sizes of MPs.
  • It provides a result in mg/L, facilitating analysis.

Discover the key to ensuring effluents are microplastic-free with Captoplastic!



A device designed and manufactured by Captoplastic able to quantify the amount of microplastics present in a sample. 
  • Microplastic quantification in any water sample
  • Autonomous operation and user-friendly equipment
  • Patented techology tested and verified in all kind of water
  • Cost-effective and rapid processing solution

Captolab’s innovative technology make it essential equipment for microplastics control in water. 


This starter kit is designed to allow up to 25 tests. It contains all the consumables necessary to perform the 25 tests, and limited access to 25 entries to the Captoplastic server hosting an application software for microplastic (MP) calculation. It also provides detailed instructions on the laboratory process to follow, as well as recommendations and safety measures. Our main goal is to provide our clients with the opportunity to discover how our method works and confirm its internal effectiveness. After evaluating the method and considering the volume of tests they conduct annually, our clients can make an informed decision about which product from our catalogue best suits their needs.


To facilitate microplastic analysis, we offer a license that provides access to our sophisticated software developed by Captoplastic. With our license, our clients have access to software to perform detailed water sample analysis, allowing them to obtain precise information on microplastic concentration, expressed in mg/L.

This provides all the information you need to make decisions regarding water management and protection.


We offer a kit that provides the necessary consumables to perform 25 measurements. This kit is designed to complement the products mentioned earlier, ensuring our customers have all the resources necessary to conduct their analyses effectively and accurately. With the consumables included in this kit, users can carry out their measurements without worrying about the availability of necessary materials. With this approach, we ensure that our customers can use our method optimally at any time.

Products under development

At Captoplastic, our priority is innovation, and we continuously strive to find solutions to address the issue of microplastic pollution in water. In our constant quest for improvements, we are developing new products within our control line to effectively monitor and manage these micro-contaminants.

The products we have in development are:


Online Microplastic Monitoring 

With the aim of automatically monitoring the concentration of microplastics in water and ensuring continuous control of effluent quality, we are developing a fully automated system. This will allow us to accurately determine microplastic levels in the environment at all times, helping us identify periods of peak concentration of these contaminants. This system will be installed directly on the effluent, providing online monitoring that integrates directly into the water stream to be analysed.


Microplastic Control Equipment for Drinking Water

With the upcoming implementation of new regulations, controlling microplastics in water intended for human consumption has become indispensable. In response to this need, at Captoplastic, we are working on developing specialised equipment that can sample and facilitate the control of microplastic presence in drinking water. This equipment is designed to eliminate the need for filtration steps, thus simplifying the control process and ensuring the quality of the water we consume.
