CBT Studies and Papers

Tested extensively in the field and in labs by independent  parties against gold standard testing methods that detect E. coli, the Compartment Bag Test (CBT) gives results comparable with more complicated, expensive and less portable tests. Studies have been done in a variety of locations and environments around the world by academic institutions, national government agencies, international NGOs and United Nations agencies.

Our customers have used tens of thousands of CBTs in-the-field where they obtain similar, successful results.
