Vessel, with Heater Lowered and a 4843 Controller

Series 4540 600-1200 mL High Pressure Reactors

This series of stirred reactors has been designed for users who need higher operating pressures than the 2000 to 3000 psi offered by the General Purpose Reactor, but do not require the high operating temperatures provided by the Series 4570 High Pressure-High Temperature Reactors. These reactors offer working pressures to 5000 psi (345 bar) at temperatures to 350 °C.

(Shown at Left) Model 4546C Reactor, 1200 mL, Moveable Head Style, on a Moveable Cart.

These vessels have been designed with outside dimensions comparable to the Series 4520 and 4530 Reactors so that they can use the same support system, stirrer drive and heater as these popular general purpose models. This provides not only an attractively priced high pressure/moderate temperature system, but also reactors that can be interchanged with the 1 and 2 liter sizes. The thicker walls required for higher operating pressures reduce the volumes of these reactors to 600 and 1200 mL.

These reactors can be used in either the bench top or floor stand mountings. While the 1200 mL reactor is offered as a “bench top model”, it is too tall and too heavy to be handled comfortably on a standard height bench top. It is recommended that the floor stand support option should be selected unless the user has an “adjustable bench top” which will accommodate the overall height of the 1200mL systems.
