The HI70640L is a highly effective cleaning solution specially formulated for use with pH electrodes that become coated with milk deposits. Electrodes can become contaminated through use and may produce inaccurate results, even when they appear to read correctly in a pH buffer. Hanna’s cleaning solutions remove impurities and residues that can accumulate on electrode surfaces when immersed in samples during measurement or stored improperly. Hanna recommends cleaning the bulb and junction of your electrode regularly to ensure the probe remains clean and to help prevent junction clogging.

Hanna’s line of cleaning solutions is specially formulated to have a shelf life of 5 years from the date of manufacture when unopened.
