MM It is possible to convert most of these reactors from one size to another within the same series. This is done by substituting a longer or shorter cylinder with corresponding internal fittings including the stirrer shaft, thermowell or thermocouple, dip tube and cooling coil (if installed). In some cases, the heater will also need to be changed. The Parr Customer Service department will be happy to provide a list of the appropriate conversion parts for any contemplated conversion. MM Moveable and Fixed Head Designs The selection process starts with establishing the Four Basic...

& Select Appropriate Series Maximum Maximum Series No. Reactor Type Nominal Size Pressure psi (bar) Temperature °C Custom options available. Contact Parr’s Customer Service Department. Parr Instrument Company offers laboratory reactors and pressure vessels in sizes from 25 mL to 18.75 L. Generally it is best to select a size that will allow for 1/3 free space. This allows for some liquid expansion during the heating phase of a reaction. Operating Temperatures have traditionally been limited to 350 °C using a flat PTFE gasket. Flexible graphite gaskets have now extended the range to 500 °C....

Reactor Selection Guide 3 Confirm Standard Fittings Pressure Gage, analog type, which shows the pressure within the vessel at all times. Liquid Sampling Valve for withdrawing liquid samples through the dip tube shared with the gas inlet valve. Incoming gas can be used to clear the dip tube between liquid samples. Gas Release Valve to release gas from the reactor during or at the completion of a run. Thermocouple or Thermowell for measuring the temperature within the vessel. In small reactors, a thermocouple encased in a metal sheath extends directly into the vessel. In larger reactors, and...

5. Cooling Coil An internal cooling coil can be installed in all reactors (except the Micro sizes) to remove the heat during a reaction and/ or to cool the vessel at the end of a run. In some reactors a cooling coil is furnished as a standard fitting. In others, a coil can be added as an option in either serpentine style or alternately in a spiral style for selected models. For the micro sizes, with their limited dimensions, a cold finger may be added as an option. 6. Gage and Rupture Disc Ranges The pressure gage range must be selected to provide the resolution desired, while having a...
