HI 70300L is a storage solution prepared with reagent grade chemicals which can be used to ensure maximum performance of pH and ORP electrodes.

• Keeps the glass membrane of the pH electrode hydrated
• Manufactured specifically for pH and ORP electrodes
• Air tight bottle with tamper-proof seal ensures quality and freshness of solution
• Clearly marked expiration date and lot number

The storage solution is specifically formulated to minimise microbial growth and to prevent any effects of diffusion/osmotic from storing a probe in a solution with the highly concentrated inner reference electrolyte.
