Fixed Head Reactors
Parr now offers all of its labo-
ratory reactors in a fixed head
design. This includes all reactors
with volumes from 25 mL to 20
liters. In these reactors the head
of the vessel may remain fixed
in the reactor support stand. All
attachments to the head: gas and
liquid feed and discharge lines,
cooling water, vapor take-off
and condenser, thermocouple
and any electrical leads can
remain permanently in place.
The reactor is opened by simply
removing the split ring and low-
ering the cylinder away from the
head, leaving all of the attach-
ments undisturbed. If desired
the complete vessel assembly
can be removed from the head
support plate.
In the Series
and
reactors, the operator lowers the
heater and removes the cylinder
by hand. In the 1 and 2 liter
Series
and
reactors,
and in the 600 mL and 1200
mL Series
high pressure
models, a manual lift and sup-
port mechanism is provided for
raising and lowering the cylinder.
In the
and
Series 1
and 2 gallon units, the
Series 1 and 1.8 liter sizes, and
the
Models, the cylinder
is raised and lowered by a pneu-
matic lift mechanism.
