Series 5100 Low Pressure Reactors
T
he Parr series 5100 Low Pressure Reactors
are offered in response to users requests for:
1. A system for running reactions similar
to those that have been conducted for
many years in the Parr shaker, but which
offer stirring for better scalability, higher
operating temperatures and pressures,
and more extensive reactor controls and
instrumentation.
2. Reactors for elevated pressures with
glass vessels that permit direct observation
of mixing action, color changes, or changes
of state.
3. Reactors designed for convenient
operation at moderate pressure and/or for
corrosion resistance.
Convenient and Easy Sealing with O-rings
and Split Ring Closures
Parr has developed a new O-ring and closure
system to accommodate the requirements of this
unique glass-to-metal seal and support, which is
convenient to use. A face seal-type O-ring design
is used with the proven and popular Parr split
ring closure. For this application a special gasket
groove was designed to retain the O-ring on
the head of the reactor when it is opened. A full
range of O-ring materials is available for chemi-
cal compatibility with reactants, products and
solvents.
The split ring for the glass
vessel is padded with high
temperature plastic cushions so
the glass vessel does not come
in direct contact with the metal
split ring. Six sealing screws are
tightened only finger tight to
develop the seal on the O-ring.
The split ring snaps together
with latches to provide a secure
and positive closure.
The alternate metal cylin-
ders use a different split ring
designed to handle the higher
working pressure of the metal
vessels.
Positive Agitation by High
Torque Magnetic Drives
These reactors are equipped
with Parr magnetic drives to
provide a trouble free internal
stirrer. These drives have been
designed and tested to routinely
deliver 2000 hours of operation
without service.
Internal Stirrers
The standard internal stirrer for these vessels
is a turbine type impeller. These impellers have
been designed to provide good axial mixing to
keep any solid particles up in suspension and to
provide good gas distribution through the liquid
phase.
A gas entrainment impeller is available as an
alternate agitator for those users whose primary
need is gas re-circulation from the head space of
the reactor through the liquid phase.
Standard Reactor Fittings
The head of each glass reactor is equipped with:
• Pressure gage, 3-1/2 inch diameter, calibrated
0-200 psi and 0-14 bar
• Gas release valve
• Gas inlet valve
• Liquid sampling valve
• Internal thermocouple
• Internal cooling loop – standard 300 mL to 1.5 L
• Internal stirrer with magnetic drive
• Heads intended for use with glass cylinders
are equipped with spring-loaded relief valves
adjustable between 50-150 psi.
• All heads are equipped with a rupture disc
rated for 1000 psi.
• Internal fittings are T316 Stainless Steel with
PTFE coating.
