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

No difference in the measurements. We have used both in our corrosion measurements including those in bacterial media. The Vycor was easier to clean with less biofouling (for our experiments).
I agree that both work well in most applications. Except for high resistance media, I prefer the porous Vycor because, as noted above, it is easier to clean and usually doesn't get as contaminated as the higher surface area frits. The greater porosity of the ceramic frit is an advantage in some instances where a lower resistance and higher flow are required.
