Reaction Vessels
Each side of the Reactor Unit contains a reaction vessel bank where
10
vessels can be
mounted, for a total of
20
synthesis positions. The reaction vessels are clear Teflon
tubes, and are disposable
-
intended for one time use.
A
frit is pre-installed in the bottom
of each reaction vessel. The reaction vessels are available in either
5
or
10
rnL
sizes.
Above each reaction vessel bank is the Upper Manifold, which contains fluidic
pathways which access the reaction vessels. Located below the reaction vessel bank is
the Lower Manifold, which is used to control reaction vessel draining. Both manifolds
have male fittings over which press into the Teflon Reaction vessels. By lowering the
Upper Manifold over the bank of RVs, the
rv
tube ends press over the male fittings of
both upper and lower manifolds, creating a leak-tight seal for the reaction vessels.
Frit
The frit is a teflon filter that is installed in the bottom of each reaction vessel. The frit
allows for draining of solution from the reaction vessels while containing the solid
support resin within the vessel.
Heating and Cooling
NOTE Reaction Temperature parameters may be set using the Control Unit display
and keypad. For instructions on setting the temperature parameters, see Operating the
Quest
210,
Temperature Control.
Heating and Cooling Block
The heatinglcooling blocks are aluminum plates mounted behind the reaction vessel
holders on each side of the instrument. When RVs are mounted on the instrument they
are in contact with the heater block.
Heat is provided by a resistive heater mounted inside the heater block. Cooling is
accomplished by using a recirculating chiller to flow cold liquid (such as ethanol)
through a channel mounted at the rear of the heater block. Each reaction vessel bank on
the Quest, (Side
A
and Side
B)
can be set to two independent temperatures.
