GroLine General Purpose Cleaning Solution (230 mL)

This GroLine-formulated cleaning solution is specially designed to keep pH and ORP electrodes performing at their best. Over time and through repeated use, electrode surfaces—especially bulbs and junctions—can accumulate mineral residues or sample contaminants, which leads to drift and inaccurate readings. A quick 15–20 minute immersion in this solution dissolves deposits and prevents junction clogging, ensuring consistent calibration integrity. The bottle arrives hermetically sealed to preserve freshness and integrity, with both lot number and expiration date clearly labeled. Unopened, it remains stable and effective for up to five years from the date of manufacture—making it a convenient and reliable choice for regular maintenance.
