Reactors have wide applications in many branches of chemical technology in various industry such as hydrogenation reactions in pharmaceuticals, polymerization reactions which requires special stirring to deal with high viscosity in polymer industry, development of corrosion inhibitors for injection into the wells in petroleum and petrochemicals, catalytic hydrogenations in Catalyst Development and Testing, simulation of commercial reactions in the laboratory for teaching purposes.

Laboratory reactors give the users more control over chemical reactions, as well as offering many other benefits that can be named:
- Save operation time, users can step away to do other experiments after setting reactions.
- Enhance safety over manual reaction set-ups.
- Give higher reaction yields and more reliable results as conditions like temperature and pressure are precisely controlled.
APPLICATIONS OF LABORATORY REACTORS:
With many benefits which significantly improve productivity and safety in the labs, users should consider investing in and using reactors for your lab if you are working on the following applications:
PARR REACTOR PRODUCTS:
Fisher Scientific is proud to be a distributor for Parr Instruments Company in Singapore, which offers wide ranges of reactors. With more than 100 years on the Scientific Instrument market, Parr reactors and pressure vessels include both standard designs and custom-built equipment in laboratory to mini-pilot plant sizes.
Parr’s product lines are:
Stirred Reactors
Multi Reactor Systems
Non-stirred Pressure Vessels
Tubular
Shaker Hydrogenators
Other than reactors, Parr is also well-known for their calorimeters which are used for testing a variety of solid and liquid fuels, foodstuffs and other combustible materials. Many unique designs and highly automated instrumentation have been added to its expanding lines of fuel testing instruments.
SELECTION GUIDE FOR STIRRED REACTORS AND PRESSURE VESSELS:
1. Establish 4 Basic Specifications:
a. Maximum Operating Pressure
Parr Vessels 600 mL and under in volume are typically rated for 3000 psi, and vessels 1 L or larger are typically rated for 1900 psi. Parr also offer 5000 psi versions of models up to approximately 2 L, and 3000 psi versions of models up to 5.5 L.
b. Maximum Operating Temperature
Traditionally, the choices here have been up to 350 °C for vessels with PTFE gaskets and up to 500 °C for flexible graphite (previously metal) gaskets. Parr added the option of a self-sealing O-ring closure for general purpose vessels over a full range of volumes. These quick closing designs are limited to 225 °C, although this can be raised to 300 °C with special O-ring materials.
c. Vessel Size Standard
Parr stirred reactors are offered in many sizes ranging from 25 mL to 18.75 liters (5-gallon). It should be noted that these volumes refer to the free space in the vessel, and for safe operation the maximum liquid charge held in the vessel typically should not exceed two-thirds of the available free space in sealed batch operations.
d. Material of Construction:
Parr reactors are normally made of Type 316 Stainless Steel, but they can be made of other alloys as well. The list of available materials of construction includes:
Type 316/316L Stainless Steel
Alloy A-286, Alloy 20, Alloy 230, Alloy 400
Alloy 600, Alloy 625, Alloy B-2/B-3, Alloy C-276
Nickel 200
Titanium Grades 2, 3, 4, & 7
Zirconium 702 & 705
2. Select Appropriate Series:
3. Confirm Standard Fittings and Specify Detailed Options:
There are a number of options to be considered and selections to be made in order to complete the specifications for a reactor. Based on your applications and preferences, you will need to choose the Sealing Style, Mounting Style, Support Stand, Stirrer Type, Cooling coil, Gage and Rupture Disc Ranges, Certifications and Custom Options.
