HI-70300L PH Electrode Storage Solution, 500 Ml

HI-70300L Electrode Storage Solution (500 mL)

The HI-70300L is a storage solution prepared with reactive grade chemicals that can be used to ensure the maximum performance of your pH and ORP electrodes.

After cleaning your electrode with one of our wide variety of cleaning solutions, rinse it with tap water and soak the electrode in Hanna’s specially formulated Storage Solution (HI-70300 or HI-80300) before measuring. If the Storage Solution is running low, pH 4.01 or pH7.01 buffer solution can be used.

Between measurements, storage solutions minimize microbial growth and keep the sensor tip and reference junction moist and clean, as well as diffusion and osmosis effects.
