The wait is over!

Since our victory at the 2018 MIT Water Innovation Prize for developing the simplest and cheapest E. coli test yet, our team has been working tirelessly to make the Oasis test available to customers worldwide.

A randomized controlled trial performed in the slums of Kanpur, India has proved that even where poverty and illiteracy are rampant, people are able to use the Oasis test and interpret its result. A UNICEF-backed trial has shown that the Oasis test is as accurate as the internationally accepted gold standard method, membrane filtration.

After integrating user feedback from deployments in India, the United States, Bolivia, Côte d'Ivoire and Mozambique for a wide array of clients, we will be launching the test with a revised form factor.

The new and improved Oasis E. coli Test will be launched in the Summer of 2019. This launch will coincide with the inauguration of a cutting edge production process capable of producing over 200,000 units per year and a new website that will enable seamless direct sales to individuals and organizations worldwide.

In the short term, we have the capacity to meet urgent requirements. If your project cannot wait for our official product launch, please contact us and we will ensure that your needs are met.

custom design + Manufacture of water quality tests

Our effort to design the perfect test has inspired us to work closely with leading experts, national and local governments, NGOs, industry partners, educational institutions, children and grandparents across the world. These interactions have made it clear to us that there is not and there never will be a single solution for all contexts. With this in mind, we have designed the Oasis E. coli test to meet the needs of most use cases, but are aware that certain clients will need custom designed, branded and manufactured tests to meet their needs.

Our team has extensive experience in designing and manufacturing water quality tests for a wide range of form factors, price points, aesthetic considerations, data outputs and use cases, and will be happy to work with you to design and produce a test that meets your needs.
