HI-4016-45 Sodium storage solution (500 mL)

HI-4016-45 solution is for storage of the FC300B Sodium Ion Selective Electrode (ISE). Measurement of sodium in solutions is determined by ion exchange between the selectively permeable glass membrane and the sample solution. The glass sensing membrane must remain hydrated in order to accurately determine sodium concentrations. This solution provides ideal conditions to rehydrate the membrane surface and prepare it for sodium measurements.

Before using the FC300B sodium electrode for the first time, or if reactivating it after storage, the electrode should be conditioned, soaked in storage solution, and then tested. The sodium ISE can also remain in HI-4016-45 storage solution for long and short term storage purposes.

Between measurements, storage solutions minimise microbial growth and prevent any effects of diffusion and Osmosis, as well as keeping the sensor tip and reference junction hydrated and clear – all important for an optimum response time and measurement.

Air-tight bottles with tamper-proof seals ensure quality and freshness of storage solution. Each bottle is marked with a batch number and expiry date.
