OMEGA's glass-bodied, refillable (RF), combination pH electrodes are for general purpose laboratory measurements. The inert nature of the glass body allows these electrodes to be used in aqueous and non-aqueous solutions at temperatures up to 110C. The PHE-1479 has a ceramic liquid junction and a saturated potassium chloride electrolyte. This electrolyte is a laboratory standard and is suitable for most measurements. The ceramic junction has a low flat rate which minimizes sample contamination from the potassium chloride solution. The PHE-1478 has a Porous PTFE liquid junction and a saturated potassium chloride electrolyte. The Porous PTFE liquid junction provides a stable, non-fouling reference contact ideal for the most demanding applications. This research grade electrode should be used when the sample has a very low or very high ionic strength, where greases or oils are present, or in biological solutions containing TRIS or large amounts of protein.
