Pyxis TMB Free Chlorine Dropper Kit

The Pyxis Lab® SP-710 offers both Free & Total Chlorine methods based on the tetramethylbenzidine (TMB) chemistry. The TMB method for Free and Total Chlorine is highly regarded as superior to the DPD method for its rapid result development and superior stability. These unique liquid reagents contain the TMB reagent for both free or total chlorine. As well as a pH buffer and a polymeric binder.

When three drops of liquid reagent are administered into the sample vial of the SP-710, the TMB reagent chemically reacts with free or total chlorine present to develop a stable yellow colored solution. The SP-710 measures the absorbance value of the resulted yellow solution to directly determine the free or total chlorine concentration in the sample as high as 2.20ppm for each method. Each kit is provided in a 30mL dropper bottle which is sufficient inventory for up to 230 individual tests offering a lower cost per test than conventional DPD powder pillows.
