Series 4520 1 and 2 Liter Bench Top Reactors 

 

Series 4520 1 and 2 Liter Bench Top Reactors

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. Both fixed head and moveable vessel designs are available. 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)

(Shown at Left) Model 4525 Reactor, 1000 mL, Moveable Vessel, and 4843 Controller.

With their larger diameter, these mid-size reactors have sufficient space for special modifications, such as: an internal cooling coil, a bottom drain valve, a ball valve for a solids charging port, catalyst addition devices, condensers, electrical feed-through’s and more. Details are provided in the Options Section.

The standard stirrer drive on these 4520 Models works well for reaction mixtures with viscosity 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.
