Upon receipt of the electrode carefully remove the protective yellow plastic coating and store in 3 M NaCl.


To remove the yellow plastic coating roll down the top edge of the plastic coating, then cut with small scissors. Keep rolling and cutting until the yellow coating is removed.




1) Do not cut too deeply with the scissors or else the Teflon heat shrink tubing may be damaged.



2) Do not tug the yellow coating off the glass body or the Vycor frit maybe pulled off the end of the electrode.


3) Use of a reference electrode with bubbles lodged in the tip may prevent electrical contact with the sample solution and cause damage to the working electrode. Bubbles can be dislodged by holding the top of the electrode with one hand and tapping the electrode near the Vycor tip with the other hand until the bubbles rise to the top.    2021
