The HI-1083B is a thin glass bodied electrode with single junctions and micro bulb suitable for small samples.

Electrode Storage Solutions

To minimise junction clogging and ensure fast response time, always keep the glass bulb and the junction of your pH electrode hydrated. For benchtop meters used in the lab pour a small amount of the HI-70300 storage solution in a small beaker and lower the electrode into it making sure that the junction is covered. For portable meters, store the electrode with a few drops of HI-70300 storage solution in the protective cap.

Storage solutions are designed to keep the pH electrode hydrated while minimising growth on the electrode from bacteria and algae. Placing a probe in water will result in a growth on the electrode that might not be visible to the naked eye. This growth will affect the performance and accuracy. To minimise growth, it is recommended to use pH 4 buffer if storage solution is not available. Solutions with lower pH values can inhibit growth. If pH 4 buffer is not available, it is advisable to use pH 7 buffer.

Never store a pH electrode in purified water as it will dehydrate the bulb.
