Microwave Instructions
1)
On the first screen
select with the green screwdriver/pen select ÒChemistryÓ
2)
Once into the program,
on the right side of the screen select the ÒeditorÓ option.
This screen should give a run down of all the
parameters that you can change or
modify such as temperature, time, etc.
3)
Hit the ÒtimeÓ button and enter the desired time for your reaction
and hit ÒenterÓ.
Make sure that the time
in the left hand corner has changed before proceeding.
4)
Next select the ÒtemperatureÓ option and set the desired temperature and hit ÒenterÓ.
5)
ÒPrestirring settingÓ: If you desire, you can have your reaction
prestirred without any heating for a set time. Enter a time if desired.
6)
ÒVial CommandÓ: It is extremely important to choose the
appropriate vial size. The sizes
are on the side of the vial boxes. The smaller vials have specific adapters for
the chamber. If you are using a smaller
vial, place it in the appropriate adapter and insert into reaction
chamber. Ask me if you are unsure.
Select the appropriate vial size and hit ÒenterÓ.
7)
ÒAbsorptionÓ: Generally the absorption level is set
to normal or high. There is
another setting of extremely high. Generally the first two options should be
fine.
8)
ÒFixed Hold TimeÓ: This
is an on/off option. If ÒonÓ, your
time will not begin until the microwave reactor reaches the temperature you
have chosen.
9)
Before hitting the ÒrunÓ command, make sure that the appropriate reaction and
the vial is securely in the reactor with appropriate nitrogen flow (this should
be already set).
10) After hitting ÒrunÓ, a user screen will appear. Choose your name and hit
OK. This will
now close the reaction chamber and your reaction will begin.
11) Once finished with your reaction vessel,
salvage any items that you can and then hit the Òmain menuÓ command.
This will return you to the first screen.
Other
Points
Once the microwave
reaches 22 bar the microwave will automatically shut off and the reaction
chamber will open once cooling has finished.
If you are running a
reaction for the first time and monitor via TLC, you must replace the septa
with a new one before running another experiment if you poke a hole through the
septa!!!
Try and choose an
appropriate solvent. There is manual underneath the microwave that has a guide
where to begin with certain solvents.
Try to avoid low boiling solvents such as methylene chloride and ether.
If your tube
accumulates too much pressure and breaks, find me.
Always make sure
there is a flow of nitrogen.
If you have any
problems at all ask Schwin
