Hanna GroLine Storage Solution Sachets — 25 × 20 mL

Storage solution keeps the pH glass hydrated and the junction flowing between uses, minimizing clogging and organic growth so your meter responds fast and lasts longer. These single-use sachets (25 × 20 mL) portion it out fresh — ideal for topping up protective caps without opening a bottle. Never store an electrode in distilled or deionized water.

Single-use sachets keep calibration solution factory-fresh — every calibration uses solution that has never been exposed to air or contamination. The light-blocking foil packaging protects against UV degradation, and each sachet is marked with its lot number and expiration date. Box of 25 sachets, 20 mL each.
