STANDARDIZED. COMPREHENSIVE. RAPID.

To understand how microplastics break down, move through the oceans and freshwater systems and collect on coastlines, researchers and community monitoring groups must quantify a robust set of particle size parameters. 


Saturna is a portable, standardized imaging and illumination device that plugs in to your computer and syncs with Mariana, our web-based data analysis portal, to rapidly characterize and quantify visible microplastic particles. 


Use it to collect a robust set of size, color and categorical metrics for visible microplastic samples (>400μm) like those collected from Manta trawls, neuston nets, beach quadrat samples and community studies.

FEATURES

  • Highly standardized built-in LED lighting system provides consistent and reproducible lighting for your microplastic samples 

  • Compatible with any Windows PC and operated using our Mariana data portal   

  • Provides physical size, color and categorical data for all microplastics imaged  

  • Computer pattern recognition and sizing algorithms calculate 11 discrete size calculations for every particle  

  • Predictive color models calculate repeatable and standardized average color calculations for each particle
