3534• Dry Membrane/Junction: soak in HI 70300 storage solutionfor at least 1 hour.• Drifting: Soak the electrode tip in warm HI 7082 solution forone hour, then flush the tip with distilled water. Refill with freshHI 7071 for single junction electrodes, or HI 7082 for doublejunction electrodes.• Low Slope: refer to the cleaning procedure above.• No Slope: check the electrode for cracks in glass stem or bulband replace the electrode.• Slow Response/Excessive Drift: soak the tip in HI 7061Hanna solution for 30 minutes, rinse thoroughly in distilled waterand then follow the Cleaning Procedure above.ACCESSORIESpH CALIBRATION SOLUTIONSHI 70004P pH 4.01 buffer solution, 20 mL sachet, 25 pcsHI 70007P pH 7.01 buffer solution, 20 mL sachet, 25 pcsHI 70010P pH 10.01 buffer solution, 20 mL sachet, 25 pcsHI 7004L pH 4.01 buffer solution, 500 mL bottleHI 8004L pH 4.01 buffer solution, 500 mL FDA bottleHI 7006L pH 6.86 buffer solution, 500 mL bottleHI 8006L pH 6.86 buffer solution, 500 mL FDA bottleHI 7007L pH 7.01 buffer solution, 500 mL bottleHI 8007L pH 7.01 buffer solution, 500 mL FDA bottleHI 8009L pH 9.18 buffer solution, 500 mL FDA bottleHI 7009L pH 9.18 buffer solution, 500 mL bottleHI 7010L pH 10.01 buffer solution, 500 mL bottleHI 8010L pH 10.01 buffer solution, 500 mL FDA bottleELECTRODE MAINTENANCE SOLUTIONSHI 70300L Storage solution, 500 mL bottleHI 80300L Storage solution, 500 mL FDA bottleHI 70000P Electrode rinsing solution, 20 mL sachet, 25 pcsHI 7061L General cleaning solution, 500 mL bottleHI 8061L General cleaning solution, 500 mL FDA bottleHI 7073L Protein cleaning solution, 500 mL bottleHI 8073L Protein cleaning solution, 500 mL FDA bottleHI 7074L Inorganic cleaning solution, 500 mL bottleHI 8074L Inorganic cleaning solution, 500 mL FDA bottleHI 7077L Oil & Fat cleaning solution, 500 mL bottleHI 8077L Oil & Fat cleaning solution, 500 mL FDA bottleHI 7072 1M KNO3 electrolyte solution, 4 x 50 mL bottleHI 8072 1M KNO3 electrolyte solution, 4 x 50 mL FDA bottleHI 7082 3.5M KCl electrolyte solution, 4 x 50 mL bottle, fordouble junction electrodesHI 8082 3.5M KCl electrolyte solution, 4 x 50 mL FDA bottle, fordouble junction electrodesORP PRETREATMENT SOLUTIONSHI 7091L Reducing pretreatment solution, 500 mL bottleHI 7092L Oxidizing pretreatment solution, 500 mL bottle
