906 pH Electrodes, Buffer Solutions, Accessories w e b c o d e WW5PT012 1 2 3 4 4 5 Electrode Accessories, WINLAB ® Electrode storage bottle The proven solution to the problem of properly storing your pH electrodes. Fill the bottle with 3 moles of KCL solution and insert the electrode through the special seal, so that the electrode is well immersed in the KCL solution. This ensures that the electrode membrane is sealed in an airtight environment surrounded by the correct electrolyte. Article Order No. 1 Electrode storage bottle 250 ml 61 03 80136 incl. screw cap, special seal, 250 ml 3 mol KCL solution Spare KCl solution, 3 mol, 250 ml 61 03 80150 Electrode Storage Rack For the storage of pH electrodes. Being able to be brought in up to 5 pH laboratory elec - trodes into the glass vessels provided for it with special seal of PTFE/silicone in this rack. So pH electrodes are always stored correctly uprightly and in the suitable electrolyte.
