| Description | Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C. All of these reactors have been designed with suitable valves, fittings and modifications to the vessel Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C. All of these reactors have been designed with suitable valves, fittings and modifications to the vessel itself to operate at the higher temperature and pressure ratings. Flat, flexible graphite (FG) gaskets are used for temperatures in the higher range to 500 °C. These can be replaced with PTFE gaskets for procedures in which the temperature will not exceed 350 °C. All cart and floor stand models use ceramic fiber heaters to achieve the higher operating temperatures....

With reactor volumes of 5 mL or 10 mL, independent reactor gas filling, PID temperature control, and a choice of two closure styles, the flexibility of the The Series 2500 Micro Batch Reactor System is the smallest of Parr's family of stirred reactors and is available in a number of configurations. With reactor volumes of 5 mL or 10 mL, independent reactor gas filling, PID temperature control, and a choice of two closure styles, the flexibility of the MBS 2500 is sure to bring value to your small volume, high pressure project. Based on the popular Parr MRS 5000, the MBS 2500 offers even smaller volume options, a smaller footprint, a stand-alone control and data logging system, and a lower per reactor price. Features of the Micro Batch System 2500 include: - Three reactors with 5 mL or 10 mL volume, available in stainless steel, high-nickel alloys, titanium, zirconium, and other exotic materials
- Small 10” x 12” (25 cm x 30.5 cm) footprint, with remotely located 4848-based controller for temperature/stirring control and pressure display.
- Standard 3000 psi (207 bar, 200 bar for CE orders) @ 300 °C rating in T316 Stainless Steel
- Trusted Parr seal geometry employing either a captive PTFE flat gasket and screw cap with compression bolts, or a self-sealing O-ring with tool-free screw cap closure
- Standard head fittings to include safety rupture disc, pressure transducer, inlet/vent valve, and internal thermocouple
- 3-valve inlet manifold for control of gas addition
- Common aluminum block heater with PID control
- Individual reactor temperature monitoring
- Individual reactor pressure monitoring
- Common stirring speed via individual PTFE-or Pyrex-encapsulated stir bars

... Read More | The 8500 Series of stirred reactors, with volumes of 50 L or 100 L, are the largest reactors offered by Parr. This series expands the available volume of our standard offering by more than five times, while retaining the easy-to-use features our customers have come to expect from Parr. Ideally The 8500 Series of stirred reactors, with volumes of 50 L or 100 L, are the largest reactors offered by Parr. This series expands the available volume of our standard offering by more than five times, while retaining the easy-to-use features our customers have come to expect from Parr. Ideally suited for scale up or pilot work, the geometry, features, and operation are very similar to that of smaller Parr reactors, but with a volume intermediate between lab-scale and traditional production scale stirred reactors.
As shown below, the 4848 Reactor Controller with associated 3 zone slave box allows for electric band heater control, or a jacket can be welded on the cylinder exterior for temperature control via circulator.
The base units are available with a 725 psi (50 bar) pressure rating, though higher pressure ratings are available upon request. As with other Parr vessels, these reactors can be constructed of a variety of commercially available corrosion-resistant alloys.
Features - Maximum Pressure (MAWP), 725 psi (50 bar)
- Maximum Temperature, 200 °C
- PID temperature control with ramp and soak programming
- Variable speed motor and gear drive
- Three zoned band heater or welded jacket
- Hoist for reactor head (manual or electric options)
- Bottom drain valve (actuated or manual options)
- Control thermocouple
Standard head fittings & internals include: - FKM O-ring head seal
- Extra heavy duty magnetic drive
- Stir shaft and stirrer assembly
- Safety rupture disc assembly
- Pressure gage with optional pressure relief valve
- Gas inlet and release needle valves
- External solids charge assembly
- Spiral cooling coil
- Custom options available
