About us

HOLTRA was founded with the vision to improve particle analysis by reporting much more than size and concentration. We recognized that differentiation of particle types based on optical properties could dramatically improve the understanding of nanoparticle preparations across a range of industries.

We have realized this vision with our DAISY-NTA instrument, setting the future standard for particle analysis by providing unprecedented information about submicron- and nanoparticles.

We provide advanced instruments as well as expert analytical services. By providing scientists with better data, we make research and development work more effective. In growing medical fields such as advanced therapy medicinal products (ATMP), which rely heavily on nano-scale engineered particles, our contribution across research, development, and manufacturing will help to improve patient safety and health.
