with only new (white wire) probes. The probes with the black wires will need to be attached to the top of the meters whereas the new probes will need to be attached to the white cables that are already on the meters. <o:p></o:p></span></p>

to the meters. The black wires are attached to the top of the meter by pushing and turning. Both pH probes will have either a black o-ring (old) or a blue rubber o-ring (new) at the top of the probe to cushion it from the glass storage tube and help seal in
the storage solution. These o-rings can stay at the top of the probes while the students are taking readings. The students should only remove the probe from the storage rack, not the tube. Students should replace the probe into a test tube filled with storage
solution when done. Probe tips should not be allowed to dry out.<o:p></o:p></span></p>

should be placed in the labeled bin so that one of the prep lab staff can check them and make any necessary repairs. If a student has a broken old probe, they will need to pick up a cable when obtaining a new replacement probe.<o:p></o:p></span></p>
