Mini Bench Top Reactors Preface Scope These instructions describe the installation, operation and maintenance of Parr Series 4560 Mini Bench Top Reactors offered in sizes from 100 mL to 600 mL. They cover the basic steps to be followed for installing these reactors and describe the function of all standard components. They cover the basic steps to be followed when installing these reactors and describe the function of all standard components.

Mini Bench Top Reactors User’s Responsibility All Parr reactors and pressure vessels are designed and manufactured with great care to assure safe operation when used within their prescribed temperature and pressure limits. But . . . the basic responsibility for safety when using this equipment rests entirely with the user; who must: 1. Select a reactor or pressure vessel that has the capability, pressure rating, corrosion resistance and design features that are suitable for its intended use.
Mini Bench Top Reactors Parr Series 4560 Mini Reactors are furnished with two structural options in addition to the size, pressure range, stirrer motor, controller and similar options. These are: Fixed Head or Removable Head Vessel Design Flat PTFE Gasket or Self Sealing O-ring Closure In the fixed head design, the head of the vessel may remain fixed in the reactor support stand.
Mini Bench Top Reactors Installation Pressure and Temperature Limits The working pressure and temperature at which any reactor or pressure vessel can be used will depend upon the design of the vessel and the materials used in its construction. Since all materials lose strength at elevated temperatures, any pressure rating must be stated in terms of the temperature at which it applies. The standard material of construction for Parr Instrument Company is Type 316 Stainless Steel.
Mini Bench Top Reactors Assemble the Reactor Parr Heating Only: These reactors require at least 10 sq. ft. of workspace in a well-ventilated area with convenient access to an electric outlet, running water, air and a drain. The Parr Heating output connector is to be used only with Parr Instrument Company heater assemblies supplied with the appropriate heater power cord. 1. Set the stand in the workspace. Bolt the stand to the bench top using the holes in the base plate. 2.
Mini Bench Top Reactors 10. Note the voltage and amperage requirement stamped on the controller data plate, and then plug the power cord into an appropriate outlet. Power for these reactors should be drawn from a grounded outlet capable of carrying up to the full current rating of the reactor. 11.
Mini Bench Top Reactors Other Vessel Head Fittings Heaters Safety Rupture Disc There is a safety rupture disc attached to the head which is intended to rupture and release the pressure before it reaches a dangerous level. A metal tag wired to the safety head identifies the burst pressure at room temperature for that particular disc. A similar tag is furnished with each replacement disc.
Mini Bench Top Reactors How to Use the Vessel Removable Vessels Always remove removable vessels from the support stand before attempting to open or close them. To open the Vessel Open the gas release valve to discharge any internal pressure. For the bolted closure, loosen the six cap screws in the split ring sections. Loosen the cone pointed screw in the outer band and lower the band to rest on the table.
Mini Bench Top Reactors Pressurizing the Vessel Check all valves carefully before admitting gas into the system. The liquid sampling valve must remain closed throughout the charging procedure. The gas release valve must also be closed unless the vessel is to be purged, or unless there is to be a continuous flow through the reactor during a run.
Mini Bench Top Reactors Air Motor Variable speeds from 100 to 2000 rpm with no spark hazard can be obtained by replacing the standard motor with an A1393HC air motor assembly. This motor operates on compressed air which must be supplied at 40 psig minimum pressure with at least 10 CFM available at that pressure. It is furnished with a speed control valve and oiler, all assembled on a mounting bracket.
Mini Bench Top Reactors Explosion Proof Operation If the local safety code requires that equipment installed in the user’s laboratory must be explosion proof there are four possible ignition hazards to be considered: 1. The Motor The standard variable speed motor is not explosion proof, yet these motors are not unduly hazardous if operated in a well ventilated location where care is taken to prevent the accumulation of explosive gases or vapors.
Mini Bench Top Reactors Periodic Pressure Tests Accessories Each cylinder used in a Parr stirred reactor is tested under hydrostatic pressure to 1.3 times its maximum rating before it is released from the factory. Micrometer caliper measurements are taken during this test to check the deflection of the walls of the cylinder under pressure.
Mini Bench Top Reactors General Maintenance Notes 1. Periodically inspect all electrical wiring and pressure connections for excessive corrosion. Suspect parts should be replaced by components only supplied by Parr Instrument Company. 2. Always use appropriate wrenches on all fittings and valves. Never use pliers or pipe wrenches. 3. Head and cylinder service fixtures are available for convenience and protection of components during maintenance of your reactor. 4.
