PARR 5500 Series High Pressure Compact Lab Reactors

5521 Reactor 300mL shown with 4836 Controller

Familiar Parr Designs

All of the safety, convenience and reliability features which have been the hallmark of Parr pressure reaction equipment for more than 50 years have been incorporated into a new line of high pressure, compact laboratory reactors. (HPCL)

These new Series 5500 HPCL reactors are based upon our popular micro and mini, Series 4590 & 4560 reactors. There are four principal differences between these new reactors and their original counterparts. These are:

1. A smaller, more compact magnetic drive is installed.
2. A smaller, more compact variable speed stirrer motor is directly coupled to the new magnetic drive.
3. The larger support stand, overarm and motor have been eliminated.
4. A streamlined, lower cost temperature controller has been designed for use with these compact systems.

As a result of these changes, we are now able to offer these new reactors to users who do not require the wide variety of options and expandability provided by our Series 4500 reactors at a significantly lower cost. These new designs will be welcomed by not only investigators with limited space or budgets, but also by investigators building multiple reactor installations for combinatorial chemistry or high throughput investigations.

The reaction vessels used in these new HPCL reactors are identical to the ones furnished in the Series 4590 micro reactors and the Series 4560 mini reactors. HPCL reactors use the popular Parr split ring closure. These vessels are rated for a maximum working pressure of 3000 psi. The maximum operating temperature is dependent upon the seal selected, PTFE gasket for up to 350 °C; with FKM O-ring to 225 °C or FFKM O-ring to 275 °C.

The 25, 50, and 100 mL reactors are equipped with gas inlet and outlet valves, a liquid sampling valve, pressure gage, safety rupture disc and internal thermocouple in addition to the internal stirrer. The 300, 450 and 600 mL reactors provide an internal cooling loop in addition to these fittings.

In addition to the standard Type 316 stainless steel, the vessels for these new HPCL reactors can also be constructed from any of the standard Parr materials of construction.

These vessels are designed, built and can be certified to the ASME Pressure Vessel Code, European community P.E.D. and other appropriate local codes. Electrical safety is certified by CSA and the EC-CE mark.

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 reactor mixtures with viscosity up to 10,000 centistrokes in a 600 mL reaction vessel.

Direct Coupled Motor

A 1/17 hp variable speed motor is incorporated directly into the smaller magnetic stirrer drive installed on these reactors. The motor delivers sufficient torque to drive the magnetic coupling to its limit and provides stirring speeds adjustable from 0 to 1500 rpm. The motors are equipped with a tachometer pickup to provide a signal to the optional tachometer display module which can be installed in the 4836 Controller.

New Heater / Reactor Support

A new heater that also serves as the vessel support has been designed 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 replaceable 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.

Models 4836 Temperature Controller

Parr has developed a compact temperature controller for use with these reactors. It features a PID (proportional integral-derivative) controller with ramp and soak programming for preset temperature profiles. Each controller is furnished with a digital communications port and software for loading operating parameters and temperature profiles from a PC as well as for logging temperature data to the PC.
The controller includes a load relay capable of handling the electrical loads of all of the heaters used with the Series 5500 reactors. It also provides for control of cooling water to the reactor for exothermic reactions when a cooling coil is installed. A lock out relay will shut off all heating if the alarm temperature is reached. This controller also includes the motor speed control for the variable speed motor and can be expanded to include a tachometer to provide a digital display of the stirrer speed.

Alternate Controllers Available

The Series 4840 Controllers used with the standard Parr line of medium and high pressure reactors are also available for use with these reactors. These offer the user options for cascade control, redundant temperature control, digital pressure read out, stirring speed read out, motor current draw, and analog or digital outputs not available on the 4836 controllers.

Up to eight High Pressure, Compact Laboratory Reactors can be controlled with a single 4870 Process Controller.

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 options and accessories 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 certainly 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.
