5000 Multiple Reactor System (MRS)
The vessel valves and accessories are
designed for maximum operating pressures
up to 3000 psi at operating temperatures up
to 300 °C. A system with 45 mL vessels is also
available.
Stirring System
All six vessels are stirred with a single mag-
netic stirrer system specifically designed and
built for this application. The magnetic drives
and fields are focused on the stirrer bars within
each vessel. High strength compact magnets
are used to provide coupling forces which will
operate through the heaters and vessels. The
stirring speed of the stirrer bar is variable from
0-1200 rpm. All vessels will have the same stir-
ring speed during a single run of the apparatus.
This arrangement ensures that the difference in
reaction rates between vessels run in parallel
are due to set conditions other than variations
in stirrer speed.
Heaters
The external heaters surround the vessel
walls for rapid and uniform heating and tem-
perature control. Each vessel is individually
temperature controlled. The 250-watt heater
used on each vessel produces heating rates up
to 15 °C per minute.
T
he Parr Series 5000 Multiple Reactor System
has been designed to provide an integrated
system for running multiple reactions simul-
taneously and applying the principles of high
throughput experimentation to reactions con-
ducted at elevated temperatures and pressures.
The principle features of the new instrument
include:
• Six reactors with internal stirring.
• Operating pressures to 3000 psi.
• Operating temperatures to 300 °C.
• Individual temperature control.
• Continuous individual pressure monitoring.
• Computer control and data logging
• Manifold system for rapid turn around and to
allow two different input gases.
• Volumes and reactor geometry designed for
three phase reactions.
• Flexible Control Software.
Stirred Batch Reaction Vessel
This multiple reaction system has been
designed around a vessel with 75 mL total vol-
ume. This will accommodate between 15 and 40
mL of liquid reactants which is close to the mini-
mum volume appropriate for heterogeneous
catalytic reactions.
