Rinse the plastic vessel with water sample, fill to the 5 mL mark and replace the cap. [. . . ] The Hanna Chloride Test Kit is equipped with all you need to determine chloride level of water. The design makes the kit easy to handle and, except for HI 3815 Mercuric Nitrate solution, practically prevents accidental injury or damage due to spills. Note: mg/L is equivalent to ppm (parts per million). x 100 = Cl ­ Note: push and twist pipet tip onto tapered end of syringe ensuring an air-tight fit. To improve the accuracy of the test: use a 5mL pipette for HR or 50mL pipette for LR to deliver the exact volume of sample to the plastic vessel. After use, rinse the calibrated plastic vessel a couple of times with water, or it may become permanently stained. www. hannainst. com SPECIFICATIONS · While swirling the vessel, add the Nitric Acid Solution dropwise until the solution turns yellow. · Take the titration syringe, and push the plunger completely into the syringe.
