We are on TV

Analytical Spheres was recently featured on "PM-Wissen" on Servus TV, highlighting our innovative technology in contamination control in the aerospace industry.



Innovation for Cleanroom industry

Our cutting-edge Analytical Spheres offer a revolutionary solution for Cleanroom contamination control. Designed specifically for the clean room industry, these high-precision particles provide real-time, accurate, and reliable tracking of contaminants, enabling you to optimize your cleaning procedures and maintain an ideal environment.




Microencapsulation is the process of producing microcapsules, which are small carrier systems that transport active substances. The technology involves enclosing active ingredients within a protective shell. In general, there are two types of microencapsulation:

Encapsulation with no release, where microcapsules are protected from the external environment, prevents unwanted reactions and enhances its properties, such as non-stick behavior.

Encapsulation with release where a sustained, precisely controlled release of active ingredients is required over a long period of time, improves the overall stability and effectiveness of products such as drugs.

Analytical Spheres
Low-aggregated, UV Active Powder

Our team of passionate experts with years of knowledge and expertise has developed a microcapsule powder that combines precise particle sizes and low aggregation properties. The invention led to our innovative Analytical Spheres technology, designed to enhance quality control measures in major industries.

Engineered by Ophelia Microcapsules, the dry bulk, fluorescent material with rheological characteristics that allow the microspheres to spread evenly over a surface allowing statistical measurements. The technology creates novel contamination and cleanliness control applications, allowing for quantitative and visual real-time analysis for sensitive measurements in every environment and according to high standards.
