| Description | 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

They can be furnished with either a self-sealing, O-ring closure for working temperatures up to 225 °C or with a flat, PTFE gasket for higher temperatures to 350 °C. An optional HP (High Pressure) flat gasket version has These are the largest of the Parr Reactors that can be handled on a bench top. They can be furnished with either a self-sealing, O-ring closure for working temperatures up to 225 °C or with a flat, PTFE gasket for higher temperatures to 350 °C. An optional HP (High Pressure) flat gasket version has been added for maximum allowable working pressure of 2900 psi (200 bar) at 350 °C. Both fixed head and moveable vessel designs are available. An optional pneumatic lift is available for the heavier 2 liter cylinder and heater.
With their larger diameter, these mid-size reactors have sufficient space for special modifications, such as: an internal cooling coil, bottom drain valve (not on 2 liter bench top), ball valve for a solids charging port, catalyst addition devices, condensers, electrical feed-throughs and more.
The standard magnetic stirrer drive on these 4520 Models works well for reaction mixtures with viscosities up to 25,000 centipoise. For heavier stirring loads, these reactors can be equipped with larger magnetic drives, more powerful motors, and drive trains capable of delivering additional stirring torque....

Although they are called “Mini” reactors, they offer a range of sizes large enough to work with significant sample sizes, yet small enough to be handled with ease by all operators. They are made in both fixed head and moveable vessel styles, These are the most popular of all Parr Stirred Reactors. Although they are called “Mini” reactors, they offer a range of sizes large enough to work with significant sample sizes, yet small enough to be handled with ease by all operators. They are made in both fixed head and moveable vessel styles, with a choice of either a self sealing O-ring closure with no cap screws for working temperatures up to 225 °C, or with a flat, PTFE gasket for higher temperatures up to 350 °C sealed with six cap screws in a split-ring cover clamp.
Choosing the high temperature option (HT) boosts the maximum temperature to 500 °C, but de-rates the MAWP to 2000 psi (138 bar). Standard Mini reactors can be converted to high temperature reactors (500 °C max temperature and 2000 psi MAWP) by changing the head openings to cone connections, replacing the valves with high temperature valves, replacing the gasket with a graphoil Flat Gasket, replacing the heater with a ceramic fiber heater, and replacing the split ring. Contact Parr for details.
Although internal and external space is limited in these small vessels, gas entrainment impellers, catalyst baskets, condensers and other options are available. All reactors in this series can also be easily converted from one size to another by simply substituting a longer or shorter cylinder with the corresponding internal fittings and heaters....
