Product Information

• Best ways to use pH electrodes : Proper use and maintenance of electrodes Proper use and maintenance of electrodes The electrodes currently used in the laboratory are composite electrodes, which have the advantages of being easy to use, not affected by oxidizing or reducing substances, and having a fast equilibrium speed. When in use, remove the rubber sleeve on the electrode filling port and the rubber sleeve on the lower end to maintain the hydraulic pressure difference of the potassium chloride solution in the electrode. The following is a brief introduction to the use and maintenance of electrodes: ⒈When the composite electrode is not in use, it can be fully soaked in 3M potassium chloride solution. Do not use detergent or other absorbent reagents to wash. ⒉ Before use, check the bulb at the front of the glass electrode. Under normal circumstances, the electrode should be transparent without cracks; the bulb should be filled with solution and there should be no bubbles. ⒊When measuring a solution with a high concentration, shorten the measurement time as much as possible and clean it carefully after use to prevent the measured liquid from adhering to the electrode and contaminating the electrode. 4. After cleaning the electrode, do not wipe the glass membrane with filter paper, but use filter paper to dry it, so as to avoid damage to the glass membrane, prevent cross-contamination, and affect the measurement accuracy. 5. During the measurement, pay attention to the silver-silver chloride internal reference electrode of the electrode should be immersed in the chloride buffer solution in the bulb to avoid digital jumping in the display part of the electric meter. When using, pay attention to gently shake the electrode a few times. ⒍The electrode cannot be used in strong acid, strong alkali or other corrosive solutions. ⒎It is strictly prohibited to use in dehydrating media such as absolute ethanol, potassium dichromate, etc.
