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.
4577 High Temp/High Pressure Reactor, Floor Stand, Fixed Head, 1000 mL w/Heater & Pneumatic Lift
4575B High Pressure/High Temperature, 500 mL, Moveable Vessel Assembly
4571 – 4572 Reactors
These are 1000 and 1800 mL moveable head reactors mounted in movable carts.
4577 – 4578 Reactors
These are 1000 and 1800 mL fixed head reactors mounted on a floor stand with pneumatic lift.
4575 – 4576A Reactors
These are 500 and 250 mL bench top reactors with 5000 psi (345 bar) and 500 °C ratings. They are available as either moveable or fixed head vessels.
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.
