PARR 5100 Serisi Düşük Basınç Reaktörleri

Series 5100 Low Pressure Reactors

The Parr series 5100 Low Pressure reactors are offered in response to users requests for:

A system for running reactions similar to those that have been conducted for many years in the "Parr shaker", but which offer stirring for better scalability, higher operating temperatures and pressures, and more extensive reactor controls and instrumentation.

Reactors for elevated pressures with glass vessels that permit direct observation of mixing action, color changes, or changes of state.

Reactors designed for convenient operation at moderate pressure.

Positive Agitation by High Torque Magnetic Drives

These reactors are equipped with Parr magnetic drives to provide a trouble free internal stirrer. These drives have been designed and tested to routinely deliver 2000 hours of operation without service.

Internal Stirrers

The standard internal stirrer for these vessels is a turbine type impeller. These propellers have been designed to provide good axial mixing to keep any solid particles up in suspension and to provide good gas distribution through the liquid phase.

A gas entrainment impeller is available as an alternate agitator for those users whose primary need is gas re-circulation from the head space of the reactor through the liquid phase.

Fixed Head Mounting

These vessels have been designed with the fixed head style. With this moutning style, the entire sealed vessel can easily be removed from the support and drive system for charging in a glove box, product recovery, and cleaning. This mode of operation will be attractive to users who intend to operate fairly simple batch systems or who need to prepare the vessel in a special atmosphere.

Alternatively the user can choose to leave the head in place in the support stand and simply drop the reaction cylinder away from the head of the vessel. In this mode, all attachments to the head (gas and liquid feeds, discharge lines, cooling water, condensers, and instrumentation leads) can remain permanently attached to the head of the vessel.

Standard Reactor Fittings

The head of each glass reactor is equipped with:

Pressure gage, 3½ inch diameter, calibrated 0-200 psi and 0-14 bar
Inlet tube
Gas release valve
Gas inlet valve
Liquid sampling valve
Internal thermocouple
Internal cooling loop – standard 300 mL to 1.5 L
Internal stirrer with magnetic drive
Heads intended for use with glass cylinders are equipped with spring-loaded relief valves adjustable between 50-150 psi.
All heads are equipped with a rupture disc rated for 1000 psi.
Internal fittings are T316 stainless steel with PTFE coating.

Convenient and Easy Sealing with O-rings and Split Ring Closures

Parr has developed a new O-ring and closure system to accommodate the requirements of this unique glass-to-metal seal and support, which is convenient to use. A face type O-ring seal is used with the proven and popular Parr split ring closure. For this application a special gasket groove was designed to retain the O-ring on the head of the reactor when it is opened. A full range of O-ring materials are available for chemical compatibility with reactants, products and solvents.

Split Ring for Glass Reactors

The split ring for the glass vessel is padded with high temperature plastic cushions so the glass vessel does not come in direct contact with the metal split ring. Six sealing screws are tightened only hand tight to develop the seal on the O-ring closure. The split ring snaps together with latches to provide a secure and positive closure.

Split Ring for Metal Reactors

The alternate metal cylinders use a different split ring designed to handle the higher working pressure of the metal vessels.

Materials of Construction

These reactors are a combination of a glass reaction vessel with a metal head, internal stirrer, dip tube, thermowell, cooling loop, and external valves and fittings, or alternatively an all metal system. The standard material of construction for the head is Type 316 Stainless Steel with PTFE coated T316SS internals. As an alternative the head and wetted parts can be provided in any of the standard Parr materials of construction.

Heating and Temperature Control

A wide variety of heating and temperature control options are available to match the individual users operating requirements.

Jacketed and Non-Jacketed Vessels

These reactors can be heated with either an attached circulating jacket or with a removable heating mantle. While we would normally expect glass vessels to be equipped with circulating jackets to maintain their transparent feature, some users may not need to heat their reactions or may prefer to use removable heating mantles when they need to work at elevated temperatures. Although transparency is not an issue with metal vessels, users will generally want to select the same heating method for metal vessels as they use for glass vessels so they can utilize the same heating and control system for both.

Heating Systems

Users who already have a circulating bath available for use with these reactors will want to order the reactor without a circulator/controller. Most laboratory circulators should be adequate for these small vessels. A stand-alone speed controller is optionally available for user’s with their own circulators. Parr offers a circulator for use with jacketed vessels. It has a 1000 watt heater and is sufficient to heat all of these vessels to the 200 ºC +/- 1 ºC maximum operating temperature. The reservoir capacity is 6L with a circulator pump capacity of 7-15 L/min. Optionally furnished with 5 L of silicone oil. Moveable electrical heating mantles are available for vessels which do not have attached circulating jackets. These mantles are available for power supplies of either 115 or 230 volt.

Size

Series 5100 reactors can be easily converted between the 160, 300, 450, and 600 ml sizes by simply changing the cylinders and wetted parts. If you plan to convert at a later time, be sure to order the stand for the largest size you plan to use so the shield and supports will not have to be replaced. In a similar manner 1 L and 1.5 L are interchangeable. While the 160 – 600 mL stand can not be converted to hold 1 and 1.5 L vessels, the larger stand can be converted to accommodate the 160 - 600 mL vessels.

Temperature Controllers

4836 Controllers

Parr has developed a compact temperature controller for use with these reactors. This controller also includes the motor speed control for the variable speed motor and can be expanded to include a tachometer to show the speed of the stirrer. Only one expansion module can incorporated into the compact controller. Users who wish to program their reactor to automatically step through a pre-set temperature profile will want to select the 4836 controller with this feature. These controllers will control either the Parr circulator or the electric heating mantles.

Series 4840 Controller Available

The Series 4840 Controllers are also available for use with these reactors. These controllers offer the user options for cascade control, redundant temperature monitoring, digital pressure read out, stirring speed read out, motor current draw, and analog or digital outputs.

Stirrer Motors

Series 5100 reactors are provided with a choice of three motors.
The standard motor is an 1/8 hp variable speed motor.
The standard stirring speed is from 0-1750 rpm. A dual pulley can be inverted to double the torque and halve the speed. An explosion proof motor (1/4 hp) is available. This motor is also variable speed and offers the same stirrer speed ranges as the standard motor. An air motor is available for users who prefer the added safety of motors which are not electrical and have available a compressed air source.

5110 Conversion Sets
Glass to Metal
or Metal to Glass

Series 5100 reactors can be easily converted between glass and metal cylinders. The conversion sets listed below include the cylinder, closure, gage and safety relief devices for the “converted to” system. These are ordered separately from the table in the literature.
