Stool specimen collection made easy.
Solutions for your research developed by experts in sanitation innovation.
Our Innovation
Stool biomarkers are an exciting and growing area of research. In microbiome research, we know that recruiting participants willing to provide specimens is critical.
However, traditional stool collection is cumbersome, often messy, and relies on substandard methods—all of which contribute to low participation.
To ease the process and advance research, we are engineering new approaches.
