官方英文资料：Parr’s 4555 Series Reactors now include models with volumes ranging from 10 to 40 liters. These large volume reactors are ideal for an initial scale-up from smaller lab-scale equipment, serving as a step before transitioning to Parr’s Series 8500 Floor Stand Stirred Reactors (50–100 L) . Another option for users desiring larger operating volumes is the use of multiple 30 L/40 L reactors in parallel . This strategy may offer advantages such as higher temperature and pressure ratings compared to the 8500 Series, along with potential cost savings.

官方英文资料：Models 4555 – 4558 are available in 10 and 18.75 liters with operating temperatures of 225 °C, 300 °C, or up to 350 °C and are offered in either the moveable or fixed head design. In the moveable head design, the vessel is held in a support system which minimizes the physical effort required to handle these heavy components. The hoist is attached to a support column which provides a convenient means for lifting the head and cylinder out of the stand. These components may be transferred to the holding position on the right side of the stand. Vessels equipped with a bottom drain valve typically remain in the heater most of the time but can be lifted out when necessary.

官方英文资料：The fixed head support stand features hinged split-rings that swing to either side allowing the head to remain fixed to the stand while a pneumatic lift allows the cylinder to be raised and lowered. When lowered, the cylinder can be slid forward for cleaning and servicing.

官方英文资料：The 4559 models are available in 30 and 40 liters and come standard with operating temperatures up to 350 °C. The 4559 models are only available with a fixed head design.

官方英文资料：The Series 4555 Reactors come in two configurations:

官方英文资料：Moveable Head Reactor in a Table Floor Stand with Manual Hoist (10 & 18.75 L only) Fixed Head Reactor with Floor Stand and Pneumatic Lift (10 – 40 L)

官方英文资料：These large format reactors are generally used for pilot scale or for custom chemical production purposes, usually with a variety of attachments added to the basic units. Various heaters , larger motors , higher torque magnetic stirrer drives for high viscosity applications, condensers , solids charging ports , bottom drain valves , and Tilt-to-Empty features are available.

官方英文资料：Modified versions of these units are available with higher working pressures and temperatures.
