General purpose plastic bodied glass (non-refillable) electrode, suitable for most investigations.

Filled with Ag/AgCI gel electrolyte

For use with pH Adaptor (Order No. 3125).

See the pH Pack (3125PK) for the complete sensor.
 

Keep the pH sensitive membrane wet at all times. For the ion exchange process to occur properly, the glass needs to be hydrated. Check and maintain the level of storage solution [equal volumes of pH 4.0 buffer and between 3.5 to 4 M Potassium Chloride (KCl) solutions (1:1 v/v)].

Storage solution recipe: Add 29 g of KCl to 100 cm³ of water (4 M KCl). Add to 100 cm³ of a pH 4 buffer solution.
