Acidity electrode maintenance, upkeep, and preservation plan

HI70300 Customized specialized electrode preservation solution
specifications：20 mL × 4；120 mL、230 mL、500 mL
Electrode preservation solution is an important step in ensuring the optimal performance of acidity pH electrodes and redox ORP electrodes.

Specially formulated with high-purity chemical reagents and high-quality deionized water, rigorously certified with various measuring tools and containers, carefully formulated in a temperature and humidity environment that meets the requirements, and traceableNISTstandard reference materials（SRM）；

Hanna brand electrode preservation solution, formulated with a special formula to minimize bacterial growth on the electrode, adopts a unique tamper proof sealing setting to ensure the quality and freshness of the electrode preservation solution,

If the acidity electrode glass sensing membrane or dialysis membrane head is found to be dry, the electrode should be soaked inHI70300At least in the electrode preservation solution1More than an hour.
aciditypHElectrode and oxidation-reductionORPAfter use, the electrode must be cleaned with a specialized electrode cleaning solution. For the cleaned electrode, it should be filled withHI70300Electrode preservation solutionHI740200The electrode protection kit is installed on the electrode sensor to ensure that the electrode sensor is immersed in the electrode preservation solution.

After using the electrode, it is necessary to immediately use a specialized cleaning solution, which is an indispensable step to ensure the service life and response time of the electrode. According to the different samples being measured, the corresponding electrode cleaning solution should be selected:
HI7061Universal electrode cleaning solutionSpecifications:20 mL × 25； 120 mL、230 mL、500 mL
The electrode is soaked in conventional electrode cleaning solution for about30Minute, can dissolve mineral residues and other common attachments
HI7073Protein electrode cleaning solutionSpecifications:230 mL、500 mL
The electrode is immersed inproteinElectrode cleaning solution approximately15Minute, effectively dissolves proteinQualitative residue
HI7074Inorganic electrode cleaning solutionSpecifications:230 mL、500 mL
The electrode is immersed in inorganic electrode cleaning solution for about15Minutes, effectively removing residues at the dialysis membrane site to prevent membrane blockage
HI7077Oil electrode cleaning solutionSpecifications:230 mL、500 mL
To clean oil or grease attachments, it is necessary to use the correct chemicals to dissolve them and ensure that the electrodes are not affected
