Which reference electrode to select for electrochemical measurements? The one with Vycor or ceramic frit?

[Emma Stella Jonsson]

Hi. Is there any significant difference in quality and accuracy between reference electrode with Vycor frit (porous glass attached with heat-shrink tube) and the one equipped with ceramic frit (molten in the glass tube) like in this example https://redox.me/collections/all/products/ag-agcl-reference-electrode-70mm

I suspect it won't matter much in most applications.
The only real way to find out if it makes a difference in the system you are using is to try both.
