Compact Mini Bench Top Reactors PREFACE Scope These instructions describe the installation, operation and maintenance of Parr Series 5500 Compact 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 are intended to be used in conjunction with several related instruction sheets listed on the previous page.

If present on the product, the user must consult the appropriate part of the accompanying product literature for more information. This CAUTION symbol indicates that the surface may be hot. Protective Earth (PE) terminal.
Compact 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.
Compact Mini Bench Top Reactors INSTALLATION Flat PTFE Gasket Self Sealing O-Ring Closure The flat gasket is held in a recess in the vessel head and a machine pilot on the cylinder closes the recess to completely contain the gasket. The split ring closure used with this gasket has six cap screws which must be tightened to develop the loading on the gasket. The self sealing design features an O-ring retained in a groove on the vessel head.
Compact Mini Bench Top Reactors Pressure and Temperature Limits Working pressures up to 3000 psig (200 bar) maximum are permissible in these Mini Reactors when constructed of Type 316 Stainless Steel and equipped with a magnetic stirrer drive. Pressure limits for reactors made of materials other than Type 316 Stainless Steel can be obtained from customer service.
Compact Mini Bench Top Reactors Assemble The Reactor These reactors require at least 3 sq. ft. of work space on a sturdy bench or table in a well ventilated area with convenient access to an electric outlet, running water, and a drain. If the tabletop is not heat resistant it would be ideal to provide an insulated pad on which to set the vessel when it is hot. 1.

Compact Mini Bench Top Reactors IDENTIFY THE VALVES Gas Inlet Valve Liquid Sampling Valve The gas inlet valve is easily identified when the vessel is open by noting that it is connected to a dip tube which extends to a point near the bottom of the cylinder. With this arrangement, incoming gas is always introduced below the surface of the liquid. This valve includes a coupling with an “A” socket connection for attachment of the pressure hose.
Compact Mini Bench Top Reactors OTHER VESSEL HEAD FITTINGS 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.
Compact Mini Bench Top Reactors HOW TO USE THE VESSEL 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. The ring sections can now be removed, and the head with all attached fittings is free to be lifted from the cylinder.
Compact Mini Bench Top Reactors With the inlet valve open and the flow control valve on the gas tank closed, open the main valve on the gas tank only about one-quarter turn; then use the flow control valve or the valve on a pressure regulator to control the flow of gas into the vessel. After the desired pressure has been reached, close the tank valves and the vessel inlet valve and disconnect the hose at the vessel end.
Compact Mini Bench Top Reactors MAINTENANCE 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.
