pH Electrode Storage Solution 500ml

HI70300L is a storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any effects of diffusion/osmotic from storing a probe in a solution with the highly concentrated inner reference electrolyte.
