Compact Micro Reactors Preface Scope These instructions describe the installation, operation and maintenance of Parr Series 5500 Compact Micro Reactors which are offered in three sizes 25, 50 and 100 mL. They cover the basic steps to be followed when installing these reactors and describe the function of all standard components. They are intended to be used in conjunction with several related instruction sheets.

Compact Micro 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 Micro Reactors Flat PTFE Gasket or 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 Micro Reactors Installation Pressure and Temperature Limits Working pressures up to 3000 psig (200 bar) maximum are permissible in these micro 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 Parr Customer Service.
Compact Micro Reactors Assemble The Reactor 3. Plug the motor cord into the motor socket on the rear of the controller. 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 Micro Reactors Identify The Valves Other Vessel Head Fittings Gas Inlet Valve Safety Rupture Disc 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 Micro Reactors How To Use The Vessel Removable Head Vessel Flat Gasket Closure Always remove the vessel from the heater 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.
Compact Micro Reactors Do Not Overfill the Vessel Always watch the pressure gage closely when admitting gas so as not to exceed the maximum working limit. Remember that any subsequent increase in temperature will raise the pressure. Also, be sure that the amount of liquid placed in the vessel is carefully controlled. As a general rule, the liquid charge should not exceed two-thirds of the capacity of the cylinder.
Compact Micro Reactors Periodic Pressure Tests General Maintenance Notes 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 under pressure.
