2.
Slide the body (cylinder) into those grooves.
3.
Draw the assembly tight with the four threaded rods.
Make sure that the plastic “hats” are properly
seated so that the metal rods nor nuts are in contact with the metal of the end bracket.
Finger-tightening is generally sufficient to prevent leaks. After the cell is drawn together, perform final tightening
on diagonal pairs to produce a good seal against the orings.
Stirring With a Magnetic Stirrer
If you want to magnetically stir, it is best to add the stir bar during main cell assembly or before adding the
working/counter electrodes. Because of the shape of the cell bottom, egg-shaped or cross-type stir bars work
best. Small bar stirrers will turn but will not provide much stirring. If you forget to add a stir bar to your cell, you
can add a small one using a spare port.
Bridge Tube and Reference Electrode
The bridge tube fits any of the #7 ports on the top, but normal use is via the top port on the working electrode
side. It can be adjusted in its depth. Position it generally with the tip in line with the working electrode
’s
exposed area.
The bridge tube allows the reference electrode to be placed outside the test solution, isolating it from more
caustic test solutions. Ensure that the bridge tube is filled all the way to the tip with a conductive solution (the
test solution when possible) for ideal performance of the reference electrode.
Insert the reference electrode into the #11 thread at the upper end of the bridge tube. It must contact the test
solution inside the tube. Various reference electrodes that work with this system are available. Contact us for
details.
Caution:
The cell requires modest, even clamping force. Do not tighten beyond what is
necessary to prevent leaks. Overtightening can result in damage to the cell
.
