Series 5500 High Pressure Compact Laboratory Reactors
The 25, 50, and 100 mL reactors are equipped
with gas inlet and outlet valves, a liquid sam-
pling valve, pressure gage, safety rupture disc,
and internal thermocouple in addition to the
internal stirrer. The 300, 450, and 600 mL reac-
tors include an internal cooling loop in addition
to these fittings.
New Magnetic Drive
To take advantage of the new technology
available in magnets today, Parr has designed a
new compact, magnetically-coupled stirrer drive
especially for these smaller vessels. Tests show
that this new drive is sufficient to stir reaction
mixtures with viscosities up to 10,000 centipoise
in a 600 mL reaction vessel.
Variable Speed Motor
A 1/17 hp variable speed motor provides stir-
ring speeds adjustable from 0 to 1700 rpm. An
optional tachometer pickup provides a signal to
the optional tachometer display module which
can be installed in the 4848 Controller.
Heater / Reactor Support
A heater also serves as the vessel support for
the HPCL Reactors. This is an aluminum block
style heater for excellent thermal uniformity. The
cartridge heaters used in this heating block are
easily replaced if required. A stainless steel heat
shield is provided around the heating block. This
style of heater/reactor support provides a very
small footprint, ideal for limited bench space.
Model 4848 Temperature Controller
The Series 4848 Controller used with the
standard Parr line of medium and high pres-
sure reactors is also furnished for use with
these reactors. The 4848 offers the user options
for redundant temperature sensor and alarm,
digital pressure readout, stirring speed display
or control, motor load, and bi-directional digital
communication (RS-485).
Alternate Controllers Available
A single 4871 Process Controller can control
up to eight High Pressure Compact Laboratory
Reactors.
Options
As shown in the ordering guide, a variety
of options are available for these Series 5500
Reactors. In addition to the options described
here, there are a number of additional accessor-
ies such as glass or PTFE liners, special stirrers,
gages, gas and liquid feed systems, custom
valves, etc., as described in the options section
of this catalog.
Please remember that the Series 5500 reactors
have been designed and packaged to provide
the basic functions of these small laboratory
reactors and not all of the options available for
the more versatile Series 4500 Reactors can be
incorporated into these units. Investigators who
need explosion proof operation, jacketed vessels,
bottom drain valves, high torque stirrers, catalyst
baskets, etc., will need to start with a Series 4590
Micro Reactor or a Series 4560 Mini Reactor.
