Hanna Instruments HI-70300L is a storage solution prepared with reagent grade chemicals to ensure maximum performance of your pH and ORP electrodes. After cleaning your electrode, rinse with tap water then soak the electrode in the HI-70300L before taking measurements. Using this storing solution between measurements minimises microbial growth and prevent any effects of diffusion and Osmosis. It also keeps the sensor tip and reference junction hydrated and clear. This is important for optimum response time and measurement. 

Benefits

• 500ml bottles
• Certificate of Analysis is available on request
• Air-tight bottles
• Ensure maximum performance of your electrode
• Microbial growth 
• Tamper-proof seals

Each bottle of HI-70061L is packaged in an airtight bottle and a tamper-proof seal to ensure quality and freshness. The label on the bottle shows a batch number and an expiry date.

Important note from the manufacturer Hanna Instruments: pH or Oxide Reduction Potential (ORP) electrodes should never be stored in distilled or deionised water as it will shorten the life of the sensor. Also, check our range of special storage solutions. For example: Sodium ISE Storage solution.
