How do I store my pH electrode?

Download FAQ

When a pH electrode is not in use, the bulb should be kept in a wetted environment. Dehydration of the bulb will temporarily impair the electrode’s performance. The following storage procedure is recommended when the electrode is not in use.

  1. Short-Term: Immerse the electrode in 3.8M KCI solution (Broadley-James Part Number: AS-3120-C20-0500). Do not store electrode in DI water.
  2. Long-Term: Fill soaker bottle (Broadley-James Part Number: AM-1090-12) with fresh 3.8M KCI solution and insert electrode. The soaker bottle o-ring should be securely in place, and the cap should be hand tightened. Do not store electrode in DI water.
