How to avoid the electrodes keep leaking

Usually, the rapid seepage is caused by the internal pressure. After adding liquid, you can also invert the electrode to make the end ceramic core face up, and gently flick the PEEK rod to make the internal bubble float up. Insert it on a foam pad and let it stand for several minutes to release the internal pressure.                                                   If you buy a PEEK mercury oxide reference electrode, take some precautions when adding liquid. You can learn through the video on the product details page.*60mm-3019.html

How to do when the mercury oxide reference electrode broken?

Q: How to do when the mercury oxide reference electrode broken? A:  If the electrode is broken, please be sure to operate in accordance with the laboratory hazardous chemical treatment method to avoid the diffusion of mercury oxide, which is a toxic material. Description of the mercury oxide reference electrode: The mercury-mercury oxide(Hg/HgO) reference electrode is mainly used in alkaline solutions. It is an electrode composed of metallic mercury and its insoluble salt HgO and 1M KOH solution. Its electrode potential is 0.098V (25°C). The salt bridge of the Hg/HgO reference electrode is made of glass and PTFE, and the size is φ6*70mm. This size can be matched with various types of Dek Research electrochemical cells. Special attention should be paid to maintenance and storage when using the Hg/HgO reference electrode. The substance containing mercury oxide is a toxic substance, and the salt bridge solution is corrosive. Please strictly abide by the relevant laboratory safety regulati
