官方英文资料：Vessel Sizes, mL: 1000-2000 Standard 970-1900 HP

官方英文资料：Standard Pressure MAWP Rating, psi (bar): 1900 (131)

官方英文资料：Standard Maximum Operating Temp. ºC: 225 w/ FKM O-ring 300 w/ FFKM O-ring 350 w/ PTFE Flat Gasket

官方英文资料：High Pressure (HP) MAWP Rating, psi (bar): 2900 (200)

官方英文资料：Maximum Operating Temp., ºC, at High Pressure (HP): 350

官方英文资料：These are the largest of the Parr Reactors that can be handled on a bench top. These reactors are available with an FKM O-ring seal for operating temperatures to 225 °C, and FFKM O-ring for temperatures to 300 °C, or with a flat, PTFE gasket for operating temperatures up to 350 °C maximum.

官方英文资料：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. It should be noted, however, that the 2 liter, fixed head model is tall and may not be convenient to operate on a standard height bench top. We recommend using a floor stand. ( See Series 4530 )

官方英文资料：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.

官方英文资料：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.
