At present, the acidity meter electrodes used in the laboratory are composite electrodes, which have the advantages of being convenient to use, not affected by oxidizing or reducing substances, and having a fast balancing speed. When in use, the rubber sleeve and the rubber sleeve at the lower end of the electrode filling port are completely removed 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 the electrode: Spectionmycin Lincomycin Soluble Powder Spectinomycin Hydrochloride And Lincomycin,Hydrochloride Soluble Powder,Spectinomycin Hydrochloride Livestock,Spectinomycin Hydrochloride Swine Shandong Shengli Bioengineering Co., Ltd , https://www.shenglipharm.com
1. When the composite electrode is not used, it can be fully immersed in 3M potassium chloride solution. Do not dip with washing liquid or other water-absorbing reagents.
2. Check the bulb at the front end of the glass electrode before use. Under normal circumstances, the PH meter electrode should be transparent without cracks; the bulb should be filled with solution and no bubbles should exist.
3. When measuring a solution with a large concentration, shorten the measurement time as much as possible, and carefully clean it after use to prevent the test solution from adhering to the electrode and contaminating the electrode.
4. After cleaning the electrode, do not use the filter paper to wipe the glass film, and use the filter paper to dry, avoid damage to the glass film, prevent cross-contamination, and affect the measurement accuracy.
