By preventing the sensor tip and the reference junction from drying up, Hanna Storage Solution will keep your electrode in excellent shape. In order to get the best response time and outcome, it will also minimise any bacterial growth while not in use.

To maintain the best possible performance of your pH and ORP electrodes, use HI-70300L, a storage solution made with reagent-grade ingredients.

Rinse with tap water after using one of our many cleaning solutions, then soak the electrode in Hanna's specially developed Storage Solution (HI-70300 or HI-80300) prior to taking measurements. If the Storage Solution is running low, a buffer solution with a pH of 4.01 or 7.01 can be used.

Solutions for storage minimise microbial growth between measurements and prevent any effects of diffusion and Osmosis, as well as keeping the sensor tip and reference junction hydrated and clear – all important for an optimum response time and measurement.

Air-tight bottles with tamper-proof seals ensure quality and freshness of storage solution. Each bottle is marked with a batch number and expiry date.
