For use with STS Professional's Dental Unit H2O Line Test Kit.
HPC Samples for Dental Unit Water Line analysis containing residual chlorine must be neutralised with 0.1 ml of 10% sodium thiosulfate. Each 120ml sterile jar contains the correct amount of neutralising chemical to make life very easy for the operator. Simply fill the jar to the 120ml line, then invert 30 times to mix the neutralising agent, then you’re ready to fill the HPC sampler case with 18ml of this sample for incubation.
