Guardian - Residual Chlorine Test Strips

Serim® GUARDIAN™ RESIDUAL CHLORINE Test Strips provide a rapid and convenient means for indicating the concentration of chlorine bleach (sodium hypochlorite) remaining in the solution used to rinse dialysate lines following disinfection of hemodialysis equipment. The qualitative rapid screening method can be used to determine that chlorine has been adequately rinsed from the machine. The semi-quantitative method may be useful where corrective measures are undertaken on machines dispensing unacceptable levels of chlorine for extended periods and for testing containers, i.e., “bicarb jugs,” disinfected with bleach. Results of 0.5 ppm or above indicate that further rinsing is necessary. For more information refer to the Residual Chlorine product insert.
