Product Overview

HI80300L is a storage solution supplied in FDA-compliant bottles. It is prepared with reagent-grade chemicals and can be used to ensure optimum performance of pH and ORP electrodes. It is necessary to store pH electrodes in a solution to keep the glass membrane of the pH electrode hydrated. Ideally, a storage solution should be used; never store electrodes in distilled or deionized water. Hanna Instruments storage solutions are specially formulated to minimize microbial growth and to prevent any diffusion/osmotic effects from storing probes in solutions with a high concentration of internal reference electrolyte. Storing pH and/or ORP electrodes in a storage solution also keeps the junction clean. Maintaining the hydrated layer and a clear junction helps ensure fast and reliable measurements. If pH electrodes are cleaned with our cleaning solutions, we recommend soaking the electrode in HI80300L storage solution for at least one hour before measurement.

Key Features

• Special formulation: minimizes microbial growth and osmotic/diffusion effects between the solution and the internal reference electrolyte.
• Made specifically for pH and ORP electrodes.
• Expiration date and lot number: clearly marked expiration date and lot number.
• FDA-compliant bottles.
• Light-blocking bottle: prevents UV degradation.
• Airtight bottle with tamper-evident seal: ensures the quality and freshness of the solution.
• Expiration date and lot number: every bottle is marked with a lot number and expiration date; Hanna storage solutions are specially formulated, and unopened bottles are valid for 5 years from the date of manufacture.

Directions for Use

HI80300L is a solution that can be used to store pH electrodes. To ensure optimum response time, the glass sensor tip and the reference junction of the pH electrode should be kept moist and must not be allowed to dry out when not in use. Placing the electrode in a small glass container with storage solution, or replacing the solution in the protective cap, are suitable ways to store the electrode. HI80300L should also be used to rehydrate electrodes after a cleaning procedure, soaking for at least one hour before measurement.

Never store pH or ORP electrodes in distilled or deionized water. Doing so will shorten the life of the sensor.
