The QuestTMGaseous Reaction and Concentration Manifold (GRCM) is
designed for use on the Quest 210 SLN organic synthesizer, and on the
standard Quest 210 with the Lower Manifold Luer Upgrade.
The GRCM enables gaseous reactions (e.g., hydrogenation, carbonylation,
etc.) and sparging to be to be carried out. It also enables products to be
concentrated and evaporated directly, simplifying solvent exchanges and
the transition from synthesis to purification.
The GRCM consists of the following components:
Control Box. The control box has two gas inputs,athree positionvalve, a
pressuregauge, and two gas outlets eachwith a needlevalve to regulategas
flow. The gas suppliesfor concentrationand gaseous reactions connect to the
controlbox. The User selects either gas input
1,
gas input
2,
or closed usingthe
three-way valve. One gas outlet connectsto the gas deliverymanifoldvia 118"
Teflon tubing, and the other isfor usewith an additional gas delivery manifold.
Gas Delivery Manifold. The gas delivery manifoldattachesto the Quest 210
lower manifold luers and delivers gas
to
the reactionvessels. The delivery
manifoldhas a gas input, a manifoldtodistributegas to 10reactionvessels, and
10gas outletswithfemale luerswhich matewiththe malehersof the Quest 210
lowermanifold. Each gas outlet has a check-valveto preventits reactionvessel
from draining while allowinggas delivery.
Solvent
Trap
Manifold. The solvent trap manifoldattaches to the Quest210
uppermanifoldandvents the reactionvessels duringconcentration. The solvent
trap manifoldhas a portfor each reactionvessel, a manifoldto collect theexiting
gas, and an outletwhich connectsto a solventtrap.
The GRCM can be used to concentrate or add a gaseous reagent to a single
bank of ten Quest reaction vessels (10 RVs) and has a maximum operating
pressure of
10
psig (1.69 barr).
An Expansion Kit is available which provides additional delivery and
solvent trap manifolds to expand the number of parallel concentrations and
gaseous reactions to twenty (20 RVs).
