GLASS

Glass electrodes are very suitable for laboratory use. This glass can withstand many irritating chemicals and is easy to clean. Glass electrodes also allow for rapid transfer of heat to the internal reference electrolyte. Generated by reference potentialmVRelated to temperature. The faster the balance, the more stable the reference potential.

Suspended solids and proteins in food can clog traditional ceramic reference dialysis membranes, hindering the measurement circuit between the indicator electrode and internal reference, resulting in slower response time, unstable readings, and frequent electrode replacement.

Open structure design includes samples and internal componentsAg / AgClSolid gel interface (viscoelastic body) between references. This interface not only prevents silver from entering the sample, but also prevents blockage, thereby achieving fast response and stable readings.

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:
