storage solution for ph-electrodes 50 ml

PH meter anode storage fluid. The pH meter is a precision instrument. Correct use and proper maintenance are essential to enjoying your pH meter for a long time. Here are some important facts: When you buy an electrode, it is usually hydrated. First, let it soak in the storage solution for 4 hours. After each use, the sliding cap with the electrode must also be filled with its storage solution. This will keep your electrode working properly for much longer. Before the first measurement, the pH meter must be calibrated with buffer solutions. If the pH meter can only be calibrated at one point, use the buffer solution closest to your normal measurements. Be careful not to contaminate the buffer solution when calibrating. Therefore, never insert the electrode directly into the bottle, but measure it by pouring a small amount into a separate cup. After calibration, throw away the used cups, do not pour the liquid back into the bottle! Preferably, never touch the electrode, certainly not with your fingers. If you want to clean it, use only a soft cloth without rubbing the electrode..
