What is the difference between a single junction and double junction pH electrode?

pH electrodes have many options to choose from;  tip shape, junction type, shaft material and fill solution. A key difference is whether the electrode has a single or double junction. How do electrodes work? Combination electrodes work by having a sensing half-cell (AgCl covered silver wire) and a reference half-cell (Ag/AgCl reference electrode wire), these two components must be joined ...

Q: Do I need a specific Tris compatible electrode?

Tris (Tris(hydroxymethyl)aminomethane) or THAM is an organic compound used as a component of buffer solutions, especially for solutions of nucleic acids. It has a temperature dependent pH between 7.2-9 which mimics the typical physiological pH of most living organisms, it also does not react with inhibiting enzymes, making it a common buffer in biochemical, microbiological and pharmaceutical la...
