Operating the Quest 210
Starting
a
Reaction
Upper Manifold Membrane Switch
In general set the Upper Manifold Membrane Switch to "Closed when running a
reaction. This switch, when in the closed position, supplies
30
psi gas to the outside of
a membrane located with in the Upper Manifold. When pressurized, this manifold
flattens against the common pathways of the Upper Manifold, closing the pathways
between the reaction vessels on a bank, preventing any cross over of reaction vessel
contents from vessel to vessel.
NOTE With the Membrane Pressure switch in the "Closed" position, the functions of
the Manifold Control Valves are disabled.
If the Quest is connected to a gas bubbler, the membrane switch should be set to 'Open"
Also, set the switch to "Open" when utilizing Manifold Control Valve functionality
such as solvent delivery, draining, venting and/or providing an inert gas blanket.
Parallel Solvent Addition and Vessel Draining
Parallel Solvent Addition
The Quest system is equipped with an external bottle cap assembly which can interface
to a standard
4L
solvent bottle. From this bottle, parallel addition of solvent is possible.
Parallel solvent addition is typically done when adding solvent to a reaction mixture,
performing resin wash steps, and for system clean out.
This parallel addition is accomplished utilizing the Manifold Control Valves to create
a flow path from the solvent bottle to the Quest Reactor Unit Upper Manifold.
WARNING Always wear gloves and safety glasses when operating the Quest.
WARNING
Always place the solvent bottle in the plastic safety carrier.
1.
Place a
4L
bottle in a safety carrier. Insert the long tube of the bottle cap assembly
into the bottle and screw down the cap. Turn the dial on the top of the bottle cap
towards the tube marked "Pressure." Ensure that an new end-line filter is installed
