To ensure the Quest
2
10 is ready for the next synthesis it is recommended to flush the
Upper Manifold, all delivery lines, Luer Plugs and the Lower Manifold with a solvent
compatible with the synthesis. Dispose of the solvent waste in accordance with local
laws and regulations.
Flushing the System
Place the empty glass waste tank under the Quest Reactor Unit. Move the tray to its
upper most position using the waste tray handles. The silver buttons will snap out to
verify the waste tank is locked into position.
Perform three solvent washes (solvent delivery, agitation, drain) on the RV
Bank
used
for the synthesis. Select a solvent that will dissolve any solids or other residues
generated during the synthesis, in this case
THF.
Depending on the type of chemistry
used, it may be desirable to
run
a pattern of solvents through this wash process. If
a
pattern of solvents is run through the system, do at least three washes with each
solvent. It is recommended that a volatile solvent, such as acetone, be flushed
through the system last.
After the last solvent wash, let the system drain for a couple of minutes to flush
residual solvent out of the Upper Manifold.
Be sure to vent the Upper Manifold by turning the Manifold Control Valves to
"CLOSED" and "VENT".
Remove each Luer Plug and clean with the same solvent as in step
2.
Rinse out the Luer Ports with an appropriate solvent and wipe clean with a cotton
swab wetted with the same solvent as in step
2.
Replace the Luer Plugs.
Flush the Upper Manifold to waste using the following protocol,
a.
Open the Lower Manifold Drain Valves.
b.
Turn
the Manifold Control Valves to "DRAIN GAS" and "CLOSED" and allow
the delivery pathway to purge for -1 minute.
c.
With the drain valves still open, turn the left Manifold Control Valve to
"CLOSED" and turn the right Manifold Control Valve to "METERED GAS".
This will purge the other common delivery path of the Upper Manifold. Allow
the system to purge for
-1minute.
Vent the Upper Manifold by turning the Manifold Control Valves to "CLOSED and
"VENT
10.
Close the Upper Manifold by turning each of the Manifold Control Valves to
"CLOSED".
