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.

to the meters. The black wires are attached to the top of the meter by pusing and turning. Both pH meters will have either a black o-ring (old probes) or a blue rubber piece (new probes) at the top of the meter to cushion it from the glass storage tube and
help seal in the storage solution. These can stay at the top of the probes while the students are taking readings. <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 with the new replacement probe.

red flea size stir bars and vacuum tubing will be available in the window. Sarah and I will manage the microwave. Note that concentrated phosphoric acid is not needed for Day 1 and will not be provided. Each room will have a microscope. We will snag a tiny
amount of sample from the first group to obtain crude product to put under the microscope. If students observe the temperature on the digital readout going down as they heat up their melting point apparatus, they plugged the thermocouple in the wrong way.
They just need to remove it, turn it 180¢ª and reinsert it. Replacement thermocouples will also be available in the window. Each room is limited to only 6 groups due to the layout in the microwave. If a room asks for more reaction tubes, please check they don¡¯t
have more than 6 groups before handing anything out. Any questions you cannot answer should be directed to me.<o:p></o:p></span></p>
