Split Ring for Glass Reactors.
Split Ring for Metal Reactors.
Materials of Construction
These reactors are a combination of a glass
reaction vessel with a metal head, internal
stirrer, dip tube, thermowell, cooling loop, and
external valves and fittings, or alternately an all
metal system.
The standard material of construction for
the head is Type 316 Stainless Steel with PTFE
coated T316SS internals. As an alternative the
head and internal wetted parts can be provided
in any of the standard Parr materials of construc-
tion. See the 5100 Ordering Guide.
Size
Series 5100 Reactors can be easily converted
between the 160, 300, 450, and 600 mL sizes
by simply changing the cylinders and internal
parts. In a similar manner, 1 L and 1.5 L are inter-
changeable. While the 160-600 mL stand cannot
be converted to hold 1 and 1.5 L vessels, the
larger stand can be converted to accommodate
the 160-600 mL vessels. If you plan to convert
at a later time, be sure to order the stand for the
largest size you plan to use so the shield and
supports will not have to be replaced.
Heating and Temperature Control
These reactors are available with either
jacketed or non-jacketed glass cylinders allowing
for heating by either a user supplied circulator
or with a removable heating mantle respectively.
While we would normally expect glass vessels to
be equipped with circulating jackets to maintain
their transparent feature, some users may not
need to heat their reactions or may prefer to use
removable heating mantles when they need to
work at elevated temperatures. Although trans-
parency is not an issue with metal vessels, users
will generally want to select the same heating
method for metal vessels as they use for glass
vessels so they can utilize the same heating and
control system for both.
Users who are using a circulating bath that
has its own temperature control for use with
these reactors will want to order the reactor
without a heating mantle and may only need a
motor controller for stirring speed to complete
the system. Most laboratory circulators should
be adequate for these small vessels. Moveable
electric heating mantles are available for vessels
that do not have attached circulating jackets.
These mantles are for use with 115 or 230 VAC.
4848 Controller
The Parr 4848 Controller provides PC com-
munications to all of the functions housed in the
controller. The 4848 Controller offers PID Control
with auto tune, Ramp and Soak Programming,
Separate Heating and Cooling Control Loops,
Stirrer Motor Speed Control, Full or Half Power
Heater Option, Lockout Relay and Reset for Over
Temperature Protection, Expansion Modules for
Tachometer, Pressure, and High Temperature
Alarm. Users who wish to program their reac-
tor to automatically step through a pre-set
temperature profile will want to select the 4848
Controller with this feature. These controllers
will control the electric heating mantle but not a
user supplied circulator.
A2110E Motor Controller
For those who supply their own circulator for
use with glass jacketed versions of the 5100, Parr
offers The A2110E Motor Controller for setting
and controlling the speed of the stirrer motor.
Stirrer Motors
Series 5100 Reactors are provided with a
choice of three motors.
• The standard motor is a 1/8 hp variable speed
motor.
• The standard stirring speed is from 0-1700
rpm. A dual pulley can be inverted to double
the torque and halve the speed.
• An explosion proof motor (1/4 hp) is available.
This motor is also variable speed and offers
the same stirrer speed ranges as the standard
motor.
• An air motor is available for users who prefer
the added safety of motors that are not electri-
cal and have available a variable compressed
air source.
