Parallel Solvent Addition and Vessel Draining
Draining the Reaction Vessels
Reaction Vessel draining is typically done during solid phase synthesis during resin
wash steps, or when a reaction step is complete.
1. Verify that the rectangular glass waste container is installed below the reactor
assembly.
2. Toggle the "Upper Manifold Membrane" switch to "Open."
3. Set the Manifold Control Valves as follows:
drain
solvent closed

4. Open the drain valves on the lower manifold
To open the valves individually: Push down on the drain valve lever to drain the
reaction vessel. Return the lever to the closed (up) position when finished. You can
open multiple valves at the same time.
To open ten valves at the same time: Use the parallel drain lever, which fits over
all 10 drain levers, to control all 10 valves simultaneously.
5. After draining the vessels, set both Manifold Control Valves to "Closed:
