Acidity electrode maintenance, upkeep, and preservation plan

HI70300 Customized specialized electrode preservation solution
specifications：20 mL × 4；120 mL、230 mL、460 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
HI7074Oil 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

Regularly replace the electrolyte

It is necessary to regularly and timely replace the electrode filling electrolyte for the fillable electrode series. If the electrode electrolyte is contaminated or left for a long time, it will precipitate and block the dialysis membrane, making cleaning difficult and affecting the electrode response time, measurement accuracy, and service life.

Therefore, it is recommended that users use electrodes that are frequently used1-2It is also recommended to replace the electrolyte of electrodes that are not frequently used once a month6Replace the electrolyte once a month.

reminder:For the convenience of adding electrode filling solution, it is recommended to chooseHI740157Customized specialized microplastic straws,20Individual/Group

HI740200Customized specialized electrode protection cover，5Individual/Group

When using a new electrode, the top should be removed firstHI740200Protect the cover and inspect the entire electrode. If salt crystals are formed in the electrode tip and protective cover due to the evaporation of electrolyte inside the electrode through the dialysis membrane, it does not affect the normal use of the electrode, indicating that the electrode dialysis membrane is normal. Rinse it off with clean water.
During transportation, bubbles may form inside the glass ball of the electrode head. In this case, gently shake the electrode like a common mercury thermometer to remove the bubbles.
If the electrode glass induction membrane or dialysis membrane head is relatively dry, the electrode can be soaked inHI70300At least in the electrode preservation solution1One hour to keep the dry glass sensing membrane and dialysis membrane moist; Frequent soaking is beneficial for electrodes

Precautions for electrode storage

To ensure fast response time, the electrode glass sensing membrane and dialysis membrane should be kept moist at all times. After measurement or calibration is completed, the electrode should be cleaned correctly and thenHI740200Add electrode protection sleeveHI70300Electrode preservation solution up to the scale line
