New Experimental Insights

Capture high-resolution images of particles in situ to obtain deep process understanding for complex systems. Study crystallizations, suspensions and emulsions in previously unobtainable detail and reveal new insights that will power process-development.

Powerful Analytics

Transform EasyViewer into a powerful particle size and shape analyzer using optional image analysis methods in iC Vision. Monitor process changes or quantify particle size and shape with custom algorithms. Use images to verify results. Design particles faster.

Flexibility for Scale-Up

The small, probe-only instrument design and flexible mounting system can be inserted into reactors, pilot vessels and pipelines. Results from smaller scales can be compared to results from scale-up, de-risking late stage development.

Confident Deployment

Leverage auto-focus, auto-lighting, and auto-save-best-image software features to ensure every project team member can collect the highest quality images from the beginning to the end of every experiment, so that you never miss anything.
