The ChloroChek® Chloridometer® is a coulometric titrator designed to determine chloride ion concentrations in sweat samples with just 10 microliters of sweat. It displays the concentration directly in mmol/L Chloride. The sweat sample is added to an acid buffer/stabilizer working solution. Silver ions are generated by electrolysis from silver electrodes also immersed in the working solution.

The combination of silver ions and chloride ions (from the sweat sample) is a quantitative reaction that is recorded in real time, and is proportional to the chloride ion concentration in the sweat sample.

The ChloroChek is truly simple to use and provides consistent results. It performs accurate coulometric chloride titration of small sweat samples – a huge step forward in the laboratory diagnosis of cystic fibrosis in clinical laboratories that demand fast-paced accuracy at an economical cost.
