Thermo Scientific™ Orion™ Double Junction Semi-Micro Electrodes provide reliable and accurate measurements of routine samples. They are available in chemically resistant glass bodies and best suited for measuring general samples as small as 0.2mL, in test tubes and small containers.
Orion™ Double Junction Electrodes have an isolated Ag/AgCl reference system which prevents silver from coming in contact with the sample. Great for measuring TRIS buffer, sulfide and protein samples.
