Reaction Vessel Waste Draining
NOTE Change the solvent bottle frit once per week.
When a flow path is created from the Solvent Bottle Assembly delivery line to a
reaction manifold, the gas pressure forces the fluid through the tubing, via the
Umbilicus, into the reaction vessels.
Luer Ports
The luer ports are found at the top of each Upper Manifold. Each port is a beveled hole
with a corresponding plug. These ports are larger than a standard luer, but seal by the
same mechanism. Solvents, reagents, and solids may be added through the luer ports.
To remove a luer plug, twist the plug and pull it out. To re-seal the openings, twist the
plug as it is pressed into the port. The easiest method to add liquid through the luer port
is with a syringe and needle. Alternatively, a mechanical pipette can be used. Note that
a low flow of metered gas can be applied to the
RVs during manual addition through
the luer ports.
Reaction Vessel Waste Draining
Lower Manifold Drain Valves
The drain valves are located on the lower manifold and mechanically seal the lower exit
paths from the reaction vessels. Each drain valve has a lever to toggle from the closed
or drain positions. The drain lever toggles a piston, which works against a Teflon
membrane within the lower Manifold. When the lever is up, (in the "Closed" position),
the plunger pushes against the membrane, sealing the reaction vessel drain path. When
the drain valve is down, the plunger is moved back and the membrane opens, allowing
the solution in the reaction vessel to drain to waste. (Pressure must be applied to the top
head space of the reaction vessels to accomplish draining.) Each side of the reactor
assembly has ten drain valves.
You can open the drain valves individually, or in groups. The "Parallel Empty Lever"
accessory fits over all
10 drain valves on one side of the Reactor Unit. With this lever,
all the drain valves on one side of the Quest can be opened simultaneously.
