Lab-on-chip chemical sensors

The ClearWater Lab-on-Chip series sensors use sensitive wet chemical analysis methods combined with cutting-edge microfluidic technology. This results in sensors that can be deployed for extended periods (up to 1-year), conducting high-quality laboratory-grade measurements. The range currently consists of sensors for phosphate, nitrate, silicate, dissolved iron and pH.

Patented technology

Originally developed at the National Oceanography Centre (where over 200 units were built for deployment around the world), the ClearWater Lab-on-Chip range uses patented flow cell technology to create miniaturised sensitive and robust submersible chemical sensors that can be deployed in all liquid water environments.

Based on trusted chemical analyses

The sensors draw in sample water from the environment, pass it through a filter, mix it with appropriate chemicals, and measure the resulting colour change using LEDs and photodiodes. All chemical waste is stored onboard the user-swappable reagent canister.

In situ calibration

The sensors carry onboard reference standards which are analysed frequently to correct for instrumental drift. Our microfluidic technology consumes incredibly low sample volumes, meaning that reference standards can be measured as frequently as desired. It is possible for the user to take their own sub-sample of the onboard reference standard before and after deployment for their own quality-control records.

Incredibly versatile

The sensors feature a pressure compensated deep-sea housing that is rated to 6000 m, and can therefore be deployed on the surface, at the bottom of the ocean, or anywhere in between. The sensors are deployable in an incredibly diverse range of liquid water environments. Find out more by reading our Application examples and FAQ.
